PAT test and RCD protection.

[mattysupra]

Whats the rules against PAT test and how often does it need to be done.

For example- kitchen fitter using electrical goods in a domestic home or a site. Does it need testing and how often?


Can you use 240v on building site with rcd or 110v only?

Thanks in advance.

From this website: http://www.pat-testing.info/frequency.htm
Assessing the frequency of testing
The Health & Safety Executive offers no absolute rules on the frequency of the testing and inspection of portable appliances. The Memorandum of Guidance on the Electricity at Work Regulations suggests that 'regular inspection of equipment is an essential part of any preventative maintenance program', but no attempt is made to specify the intervals of time implied by the word 'regular'. The reason for this omission is obvious; different situations require different measures in order to meet the requirement that the danger is prevented. The factors which effect the frequency of testing must be assessed by the duty holder who thereby makes the judgement.

In arriving at a judgement as to the frequency of testing, a duty holder is likely to assess the following factors:-

1. The environment - equipment installed in a benign environment will suffer less damage than equipment in an arduous environment
2. Users - if the users report damage as and when it becomes evident, hazards will be avoided. Conversely, if equipment is likely to receive unreported abuse, more frequent inspection and testing is required
3. The equipment construction - the safety of a Class 1 appliance is dependant upon a connection with earth of the electrical installation. If the flexible cable is damaged the connection with earth can be lost. Safety of Class 2 equipment is not dependent upon the fixed electrical installation
4. The equipment type - appliances which are hand held are more likely to be damaged than fixed appliances. If they are Class 1 the risk of danger is increased, as the safety is dependant upon the continuity of the protective conductor from the plug to the appliance.

.

If you are doing work on a construction site then you'll need a copy of BS7671.Haven't you got one??

The answer to your question is there.

Paras 704.410 ans 411 will tell you.

I doubt you'll find any proper construction site that will allow you to use 240V tools, and they will deliberately have no 240V supplies available anywhere at all. It's 110V all the way.

What about on sites where the elecric is passed off and working plugs (240v) ?

As in a new build house that is still on a site that would need a site induction to access but has the electrisc turned on at the plugs?

Nope not got one. Any chance of a link or info of where i can get a copy please?

Thanks for that. So there is no time given then to a PAT test?

As in a new build house that is still on a site

Not likely to be using any power tools in there though, as connecting the power to the finished circuits is would be one of the last jobs in the house.

Other trades do tho.

For instance the floorlayers will be using drills, welders, planners etc.


Just try to clear up what is true and not here. Some sites say we need to use rcd protection (the CU unit already has this so dont understand that one) and other sites say 110v only even tho indoors and last trade in there.

Challenged site forman a few times on this and they never seem to be able to give a definate answer. Of course each site is different but my main point is, can you use 240v with rcd instead of 110v?

Thankyou BAS.


Not sure i need that tho as there the full regs for electrical installers? Not for someone trying to find out when and if they need there tools PAT testing?

Or as someone has said above i should maybe have a copy still if working on site?

Try before you buy

As far as I'm aware, the frequency of full visual and electrical testing of site equipment is every 3 months. A visual inspection should be carried out every month. although this should all depend upon some factors.
The sort of environment the tools are being used in. The users of the equipment (skilled, semi skilled, unskilled) The type of equipment (handheld or fixed in some way) The construction of the equipment, (double insulated or earthed).
There's lots of variables that may indicate a particular item needs a visual inspection every week (but still warrants a complete test every 3 months).

For instance the floorlayers will be using drills, welders, planners etc.

If the floors are still being laid the house isn't finished.

And if it isn't finished it won't have an owner living there.

And if it hasn't got an owner living there who will be paying the bills for the electricity supply to the house, and why?


PS - "the floorlayers will be using welders"
