temp supply

[paul b b]

Hello Chaps,

I have a shop refurb to do and have to install a tempary supply, its 3ph with 3 boards, 1 ph is going to be taken up stairs into the would be flat so it will have its own meter, so question is can i just rip out both boards and install 1 or do i need to put 3 temp supplies in?

also thought it would be a good excuse for you lot to upload some nice pics of your temp boards, i know andy had a nice one! would like 1 to copy as i have to make one on the week end.

thanks

paul

Depends what you need temps to do.

Do you need to maintain supply for upstairs?

If whole place is empty then just 1 Board would do with a good number of sockets.

This is a small one I use for basic jobs.

Temp supplies should be TT.

 

[sparkytim]

Tns quite acceptable

(Tncs NOT )

Thanks chaps,

Now I have sat in my shed doing nothing a cu that I changed for my assesment last year, but it has a stype as main switch, would it be ok to use this and just put sockets on the rcd side? Thanks again

Also what do you do for bondings?

Why can't you have a tncs temp suppy?

Thanks

Paul

all bonding is required

TNCS not to used for temp supply for same reasons as caravans etc

 

[sparkytim]

S type ok for main switch but ALL sockets need to have 30m A RCD protection, so a 30 m A RCD is usually used for a small set up or RCBOs or multiple RCDs for larger Installations to give discrimination.

Dno do not allow Pme (TNCS) to be used for Construction site installations.

If site has been stripped out then may be nothing to bond to but connect them as soon as they are available.

service pipes may still be sticking out of floor though, and would need bonding if conductive

Right, what do you do if its a tncs? This is a shop refit so on the high street and cu in celler. What's the best thing to do?

rcd it, use a rod . i.e do not connect your earthing to the suppliers earth

 

[paul b b]

thanks lee, so a hole in the floor it is!

You have an existing supply in place and I dont see the issue here with just leaving one of the fuseboards in and rigging up a few temporary rcd sockets. Disconnect all other circuits of course.
