Installing a shower.

[alanmcm]

Hi guys dont post much but have a hopefully simple enough problem.

Not long finished my time at the grand age of 34. Spent the entire time working in a quarry and commercial properties and zero time on domestic installs.

Issue is I'm doing a homer for a guy in the quarry and I'm installing a shower. Well getting the cable in for the shower, the bathroom fitters are doing the rest. Theres plenty of space in the existing dist board for the 50a MCB to go in but as the bathroom fitters wont be installing for another 4 weeks I was going to add another board in just for the shower. That way I can connect up the cable and keep it locked off, until that date and he can unlock it himself.

Ive the 10mm cable in position at the board and upstairs at the bathroom wall. If I'm putting in a new shower board do I come off the supply side of the board by putting the mains into an isco and splitting from that? Or should I connect straight into the supply side of the rcd on the main dist board?

Fell down stairs in a bungalow? See no point adding another board, ample capacity in the existing one.

The board has about 5 free ways in it left, think ill go with the majority and put the mcb in with the existing board. The RCD on the existing board is sufficient protection? I wouldn't need a 50A RCBO, a 50A MCB would suffice?

You would not install a RCBO fed from the existing RCD. The existing RCD supplying the additional MCB should be just fine, provided it tests out ok. You could install a RCBO dedicated for the shower circuit if the existing CU has room or can be simply modified to accept one fed direct from the main CU switch (assuming the CU has one). I guess this would be the ideal option, though the cost and practicality may not make it viable.

Could be a dormer

Bungalow converted with a room above the double garage. Had all the work finished and then bang down the stairs. Fair to say they didn't invite me back after that. Think I will go for the easy option and install an MCB in the board and make sure all tests meet requirements.

Much appreciated everyone thanks again.

Its always better to do a good job, at a fair price that is - safe, reliable and meets at the very least the minimum requirements. That way you can sleep at night and live a much longer happier life.

Im a member of NICEIC over here in Northern Ireland. Not sure about notifying the local authority, I usually have all my jobs planned for me and any work in the quarry I just get on with and test when installing new circuits. I record the results and hand into the office at work.

So, if you are a member - in your own name - then you just notify the job to NICEIC on line. NICEIC themselves advise the Local Authority & the customer.

Been told we don't have to actually be a member of any body or notify building control in Northern Ireland. All we have to do is notify the DNO of the additional power demand.
