Part P and outdoor wiring

[r.bartlett]

Hi guy's

We install air conditioning .The make we use always suppliers the outdoor unit then run a 3 core + E inside.

For those which need a 13a max supply in a commercial situation we would normally just spur off then through the wall to the outdoor unit.If the customer is 'price conscious'

Now in a domestic situation we would be non Part P compliant doing this. So we often just spur to the indoor unit and run a bigger interconnect (L+N are just effectively piggybacked as they don't go through the unit)

Now we have had a situation where in order to do this we spured off from a double socket on an outside wall run the cable outside (without terminating etc) back inside to the indoor unit with another fused spur. The run the interconnect as per above

Therefore we have run a cable outside but both ends are inside

Is this part P complaint??

Cheers

Richard

According to the governments directive, "outside" work falls under the scope of Part P.

NICEIC say that Parts of fixed electrical installations external to premises, will also be subject to the requirements of Part P.

However some seem to apply "outside" to installations that are remote form the house: outbuildings, such as sheds, garages and greenhouses plus garden lighting and power supplies. Not necessarily items fixed to the exterior walls of the house such as outside lights, although I think that's stretching it a bit.

Best to check with the LABC in whose area you are working for a definitive answer.

Alternatively put a 13A plug on, and plug it in.

The term "not Part P compliant" says you are doing something wrong!! All electrical work in domestic dwellings in England/Wales falls under the scope of Part P. I think you are probably getting at wether it is notifiable or not?? It would seem that what you want to do is non-notifiable going by the guidance from on page 9 here http://www.planningportal.gov.uk/uploads/br/BR_PDF_ADP_2006.pdf, that is providing the work does not involve a new circuit, or an addition to a circuit in a kitchen, special loc'n or associated with a special installation.
Putting a plug on something doesn't automatically make something non-notifiable btw

I think in this case it is not an outside supply.

In terms of the building regs I would consider any supply that exits the equi-potential zone to be an 'outside' supply.

If the cable exits the building and re enters and has suitable mechanical and environmental protection for it's outside run no problem.
If the equipment is installed in a special location or kitchen then it will be notifiable.

TBH unless you have a switched on LABC they won't be bothered

What about if the supply is fitted with a 13a plugtop. Could the owner just plug it into a socket and we wire to the outdoor unit.?

Would this be covered by Part P?

or even

What about if the owner runs the supply himself via a plugtop is that Part P?

Thanks for the input

Yeah, the installation of fixed equipment in domestic dwellings comes under the scope of part p, even when supplied by a plug and socket.
