Question 2
Are these Schuko plugs?

I suggest you don't use adaptors. Some of the appliances connected to these plugs require an earth, and whether you get an earth connection or not can depend on whether you have the plug the right way up in the adaptor.

I recommend that a suitably qualified electrician replaces the plug with the UK type.

I suggest you obtain a copy of the IEE code of practice for in service inspection and testing of electrical equipment 3 rd eddition. There is a useful table for guidance

Double insulated equipment does not get PAT tested.

Go back a step. Why the need to PAT? Look at the type of equipment, the environment, the usage and the level of risk. Visual inspections more appropriate probably.

Thanks for your feedback everyone.

Clairel,
I understand what you are saying, however, it is the retailer where this equipment is installed who is asking for the PAT certificates.

Could I also please ask you where you found out that double insulated equipment does not get PAT tested?

Lamascarelle,
I am not sure what you exactly mean by the 12V display equipment?
Is this part of the fixed wiring of the installation or is it on a "plug" and "socket" arrangement?
I am guessing the plugs you refer to are like an electric razor plug?
These IIRC are only approved for use on an electrically separated circuit in the UK.


We all know that there is NO LEGAL REQUIREMENT FOR PAT.

Now PAT is many things to many people. There are a huge number of interpretations of what is required.
I stick to the HSE guidance and that given by the IET (IEE) as this IMHO would be the definitive guidance.


Clarel,
You cannot ignore Class II appliances.
Given that nothing actually needs PAT, Class I & Class II appliances both have recognised inspections & tests which are applicable depending on your viewpoint on whether PAT is required.
A class II appliance on a construction site cannot be simply ignored and used until it kills someone.
Visual inspections ARE PAT!
This is a BIG problem over the interpretation of PAT as I see it from the HSE guidance and that from the IET.
PAT IS NOT an annual formal inspection and test by a competent person.
IMHO and it seems that of my learned colleagues at the IET and several others it is MUCH more than that.


Alan,
I would caution against the use of un-fused plugs in UK final circuit designs as they are not envisaged to operate in such a manner, thus, you can find that there could be dangerous overloads occurring.
Our final socket outlet circuits are designed to operate with a BS 1363 plug top and thus its inbuilt circuit protection.
You may find that it is not legitimate to supply equipment with these plugs on into the UK market...
There are almost certainly other pieces of legislation that would put the use of "non UK" plugs in a "unskilled" environment a situation of non-compliance.
