This is to make sure that if among the defense layers have been to cease working, there's the again-up of the second layer still in place. This makes electrical equipment extraordinarily protected to use. Appliances can be Class 1 or Course 2.
When PAT testing, it is important to very first determine the Course of the equipment as Course 1 appliances are tested otherwise from Class 2 appliances.
Relying on just how precisely the safety is provided, electrical equipment are put into 5 Courses of tools constructing and building that are Class 1, 2, three, 0, 01 Of those probably the most essential are Course 1 & 2 For completeness all the Classes are described below.
COURSE 1.
Here the protection is provided by a mix of insulation and use the mains Planet. It is best proven by referring to an electric fire that has actually been uncoupled.
Within the open plug the three cables attaching to the LIVE, NEUTRAL as well as PLANET pins. Inside the fireplace, the brown LIVE twine in addition to heaven NEUTRAL cord connect to a plastic port. The green/yellow Planet wire links to the steel scenario of the fire.
The user is protected against electric shock by the plastic insulation of the adapter. This holds the LIVE and NEUTRAL cords in position and also prevents them from touching the steel case of this electric fire. This plastic insulation of the connector is known as customary insulation.
If this basic insulation have been to stop working, state due to an excessive amount of movement of the cord the place it touches the steel occasion then the shopper of the fireplace may obtain an electrical shock if not for that the PLANET cable is present.
By attaching to the metallic occasion of the electrical fire, the PLANET wire maintains all this metal at EARTH potential. What this means is that it is troublesome to acquire an electrical shock even when the steel state of affairs of the fireplace is attached directly to the LIVE voltage. In technique a fuse would blow either in the plug or the main fuse box to defend the individual.
In summary, in Course 1 appliances the person is secured by a mixture of basic insulation and also the provision of a PLANET hyperlink, thus giving 2 ranges of security.
When PAT Testing Class 1 home equipment, the Earth Connection and Insulation Resistance checks are accomplished.
CLASS 2.
In a Class 2 equipment, the client is protected by a minimal of two layers of insulation. Subsequently, Class 2 appliances are also referred to as Twin Insulated. They do not require an Earth link.
That is finest proven by wanting inside a Course 2 electric drill which has been opened up. Inside one might see that along with the plastic connector offering commonplace insulation, there may be additional insulation offered by the plastic enclosure of the drill.
The customer is consequently safeguarded by totally different layers of insulation. When PAT testing Class 2 home equipment, simply the Insulation Resistance take a look at is executed.
Course 2 appliances are always steered by the dual field image on the rating plate.
COURSE 3
Units constructed to Class three criterion are designed to be equipped from an distinctive security isolating transformer whose output is known as Safety Additional-Low Voltage or SELV. This need to not go beyond 50 V A/C and is normally is listed under 24V or 12V. All Course three home equipment are marked by an unique icon. There is no such thing as a use a Planet in Class III appliance
The electrical security of Class 3 appliances are handled within the security separating transformer design the place the splitting up between the windings is equivalent to twin insulation. The transformer is marked as appropriating for use with Class III appliances.
COURSE 0 & 01
This kind of instruments is besides regular use in enterprise or home atmospheres. It's merely provided proper right here for efficiency.
Class zero home equipment depend simply on elementary insulation for security from electrical shock. Because of this, they don't have 2 levels of security built-in in as well as are usually not allowed for sale. The brass light revealed proper here is an example of a two wire, steel cased appliance with only fundamental insulation. There is no provision for link of a planet to the light bulb holder.
In Class 01 home equipment, there is provision for a Planet hyperlink, but it is wired with either twin core cable tv or has a 2-pin plug, so a Planet couldn't be linked. AS in Class 0 gear, one rests only on fundamental insulation for cover from electric shock. As they only have 1 diploma of protection, Class 01 home equipment are not enabled sale.
If throughout PAT testing one encounters a Class 0 or Class 01 equipment these will be fallen short.
RECOGNIZING CLASS I & CLASS II APPLIANCE
As the PAT testing carried on Class 1 as well as Class 2 appliances differ, you will need to determine one from the other. There isn't any different area of PAT testing that causes far more complication than this as well as there are lots of misconceptions bordering this. Will probably be attention-grabbing to supply just a few of these.
If there is a fuse within the plug, after that it has to be Course 1
It is constructed from metal so it must be Course 1.
The case is plastic so it needs to be Course 2
It has a three core wire so it must be Class 1
The plug has a metal Earth pin so it should be Class 1
None of the above declarations is a idiot-proof means to recognize Course I as well as Class II appliances and a few are fairly deceptive.
The simplest policy to use is the one listed below.
If the score plate has a double box after that the appliance is Class 2. If it does not after that it's Course 1.
Example - Kettle
The ranking plate on this kettle clearly has no "double-field" symbol, so utilizing our regulation, it must be Course 1. The Planet hyperlink from the plug is terminated outside metallic covering of the heating element. When PAT testing this kettle the Planet Continuity in addition to Insulation Resistance test must be executed.
Instance - Plug-prime power provide
The score plate on this Plug-top transformer clearly shows the "double field" icon, so this is a Course 2 appliance. Remember that it has a plastic Earth pin, as this isn't required for Course II. (Not all Course 2 appliances have a plastic earth pin). Just the Insulation Resistance check must be executed throughout PAT testing.
Instance - Mains extension
The rating plate on this extension is moulded within the plastic. It clearly doesn't have a "double-box" image, so it must be a Course 1. When PAT testing this enlargement lead the Planet Continuity and Insulation Resistance test needs to be performed.
Instance - Desk mild
The ranking plate on this table lamp plainly reveals the "double-field" so it's a Course 2 appliance. (Notice that this can be a Class 2 equipment that is enormously in a steel unit). The sunshine bulb proprietor is made of plastic and provides the required double insulation. Merely the Insulation Resistance check needs to be achieved throughout PAT testing.
Instance - Workdesk fan
The rating plate for this fan not only doesn't have a "double-box" icon, it also claims that the appliance must be earthed. So that is plainly a Course 1 appliance. Observe that it does not have any individual simply accessible steel.
Example - Metallic Light
If this steel lamp had a rating plate, after that it could certainly be a Class 1 appliance as it has an earth level on the lamp owner. Nevertheless, because the score plate is lacking, this might have to be stopped working.
Are Course 1 in addition to Course 2 home equipment simply as safe?
As each have 2 levels of protection built-in in, they are both safe for primary use.
Nonetheless with Class 1 an appliance, one of many layers of security is offered by the planet link. For this to be effective, the wiring in the building must be evaluated on a regular basis to verify that the Earth in the mains outlet is correctly required to the native earth possibility. That is normally chosen off the Planet sheathing of the mains cable coming into the premises, or by driving an area stake into the ground. So Class 1 appliances rely on the exterior electrical wiring within the building to totally provide the two degrees of protection.
Course 2 home equipment nonetheless at all times provide 2 degrees of safety irrespective of the standing of the wiring installation. Each layers of safety are developed right into the fashion making Course 2 appliances are a complete lot more secure than Class 1 appliances.

| New page text, stripped of any markup (new_text) | All electrical appliances utilizing mains voltage need to provide a minimum of 2 levels of security to the customer. This is to make sure that if among the defense layers have been to cease working, there's the again-up of the second layer still in place. This makes electrical equipment extraordinarily protected to use. Appliances can be Class 1 or Course 2.
When PAT testing, it is important to very first determine the Course of the equipment as Course 1 appliances are tested otherwise from Class 2 appliances.
Relying on just how precisely the safety is provided, electrical equipment are put into 5 Courses of tools constructing and building that are Class 1, 2, three, 0, 01 Of those probably the most essential are Course 1 & 2 For completeness all the Classes are described below.
COURSE 1.
Here the protection is provided by a mix of insulation and use the mains Planet. It is best proven by referring to an electric fire that has actually been uncoupled.
Within the open plug the three cables attaching to the LIVE, NEUTRAL as well as PLANET pins. Inside the fireplace, the brown LIVE twine in addition to heaven NEUTRAL cord connect to a plastic port. The green/yellow Planet wire links to the steel scenario of the fire.
The user is protected against electric shock by the plastic insulation of the adapter. This holds the LIVE and NEUTRAL cords in position and also prevents them from touching the steel case of this electric fire. This plastic insulation of the connector is known as customary insulation.
If this basic insulation have been to stop working, state due to an excessive amount of movement of the cord the place it touches the steel occasion then the shopper of the fireplace may obtain an electrical shock if not for that the PLANET cable is present.
By attaching to the metallic occasion of the electrical fire, the PLANET wire maintains all this metal at EARTH potential. What this means is that it is troublesome to acquire an electrical shock even when the steel state of affairs of the fireplace is attached directly to the LIVE voltage. In technique a fuse would blow either in the plug or the main fuse box to defend the individual.
In summary, in Course 1 appliances the person is secured by a mixture of basic insulation and also the provision of a PLANET hyperlink, thus giving 2 ranges of security.
When PAT Testing Class 1 home equipment, the Earth Connection and Insulation Resistance checks are accomplished.
CLASS 2.
In a Class 2 equipment, the client is protected by a minimal of two layers of insulation. Subsequently, Class 2 appliances are also referred to as Twin Insulated. They do not require an Earth link.
That is finest proven by wanting inside a Course 2 electric drill which has been opened up. Inside one might see that along with the plastic connector offering commonplace insulation, there may be additional insulation offered by the plastic enclosure of the drill.
The customer is consequently safeguarded by totally different layers of insulation. When PAT testing Class 2 home equipment, simply the Insulation Resistance take a look at is executed.
Course 2 appliances are always steered by the dual field image on the rating plate.
COURSE 3
Units constructed to Class three criterion are designed to be equipped from an distinctive security isolating transformer whose output is known as Safety Additional-Low Voltage or SELV. This need to not go beyond 50 V A/C and is normally is listed under 24V or 12V. All Course three home equipment are marked by an unique icon. There is no such thing as a use a Planet in Class III appliance
The electrical security of Class 3 appliances are handled within the security separating transformer design the place the splitting up between the windings is equivalent to twin insulation. The transformer is marked as appropriating for use with Class III appliances.
COURSE 0 & 01
This kind of instruments is besides regular use in enterprise or home atmospheres. It's merely provided proper right here for efficiency.
Class zero home equipment depend simply on elementary insulation for security from electrical shock. Because of this, they don't have 2 levels of security built-in in as well as are usually not allowed for sale. The brass light revealed proper here is an example of a two wire, steel cased appliance with only fundamental insulation. There is no provision for link of a planet to the light bulb holder.
In Class 01 home equipment, there is provision for a Planet hyperlink, but it is wired with either twin core cable tv or has a 2-pin plug, so a Planet couldn't be linked. AS in Class 0 gear, one rests only on fundamental insulation for cover from electric shock. As they only have 1 diploma of protection, Class 01 home equipment are not enabled sale.
If throughout PAT testing one encounters a Class 0 or Class 01 equipment these will be fallen short.
RECOGNIZING CLASS I & CLASS II APPLIANCE
As the PAT testing carried on Class 1 as well as Class 2 appliances differ, you will need to determine one from the other. There isn't any different area of PAT testing that causes far more complication than this as well as there are lots of misconceptions bordering this. Will probably be attention-grabbing to supply just a few of these.
If there is a fuse within the plug, after that it has to be Course 1
It is constructed from metal so it must be Course 1.
The case is plastic so it needs to be Course 2
It has a three core wire so it must be Class 1
The plug has a metal Earth pin so it should be Class 1
None of the above declarations is a idiot-proof means to recognize Course I as well as Class II appliances and a few are fairly deceptive.
The simplest policy to use is the one listed below.
If the score plate has a double box after that the appliance is Class 2. If it does not after that it's Course 1.
Example - Kettle
The ranking plate on this kettle clearly has no "double-field" symbol, so utilizing our regulation, it must be Course 1. The Planet hyperlink from the plug is terminated outside metallic covering of the heating element. When PAT testing this kettle the Planet Continuity in addition to Insulation Resistance test must be executed.
Instance - Plug-prime power provide
The score plate on this Plug-top transformer clearly shows the "double field" icon, so this is a Course 2 appliance. Remember that it has a plastic Earth pin, as this isn't required for Course II. (Not all Course 2 appliances have a plastic earth pin). Just the Insulation Resistance check must be executed throughout PAT testing.
Instance - Mains extension
The rating plate on this extension is moulded within the plastic. It clearly doesn't have a "double-box" image, so it must be a Course 1. When PAT testing this enlargement lead the Planet Continuity and Insulation Resistance test needs to be performed.
Instance - Desk mild
The ranking plate on this table lamp plainly reveals the "double-field" so it's a Course 2 appliance. (Notice that this can be a Class 2 equipment that is enormously in a steel unit). The sunshine bulb proprietor is made of plastic and provides the required double insulation. Merely the Insulation Resistance check needs to be achieved throughout PAT testing.
Instance - Workdesk fan
The rating plate for this fan not only doesn't have a "double-box" icon, it also claims that the appliance must be earthed. So that is plainly a Course 1 appliance. Observe that it does not have any individual simply accessible steel.
Example - Metallic Light
If this steel lamp had a rating plate, after that it could certainly be a Class 1 appliance as it has an earth level on the lamp owner. Nevertheless, because the score plate is lacking, this might have to be stopped working.
Are Course 1 in addition to Course 2 home equipment simply as safe?
As each have 2 levels of protection built-in in, they are both safe for primary use.
Nonetheless with Class 1 an appliance, one of many layers of security is offered by the planet link. For this to be effective, the wiring in the building must be evaluated on a regular basis to verify that the Earth in the mains outlet is correctly required to the native earth possibility. That is normally chosen off the Planet sheathing of the mains cable coming into the premises, or by driving an area stake into the ground. So Class 1 appliances rely on the exterior electrical wiring within the building to totally provide the two degrees of protection.
Course 2 home equipment nonetheless at all times provide 2 degrees of safety irrespective of the standing of the wiring installation. Each layers of safety are developed right into the fashion making Course 2 appliances are a complete lot more secure than Class 1 appliances.
