new build some questions

[ufkir]

Hi guys been more of an observer than a poster but need some answers if anyone can help so here it is.
i have picked up some work on a couple of new builds that were started before the recession the original sparks have went bust so im told any way i have been asked to finish the job but there are a couple things that concern me.
1 The meter box is outside on the wall and they have brought a split concentric in to the consumer unit > 3 metres
also it is not > 50mm below the surface can i fit an s type rcd from the meter to then feed a kmf.
2 The family bathroom has a 240 v fan cored through the wall in zone 1 above bath is there i think it about 2mtrs from floor but not if your standing in the bath is this okay i have a feeling that fans were okay as long as it was above a certain height in zone 1 thanks to all in advance

No problem with Low Voltage equipment being used in Zone 1, so long as it is designed for that use. 701.55

By low voltage you mean 230v?

hi alanl yeah i know its okay but i think there is a height it has to be above

 

[alanl]

Is it in Zone 1, or outside the zones?
Is it suitable for the environment it is used in?
What are the manufacturers guidelines?

Why do you think it has to be above a certain height?
I presume you mean so that it is outside Zone 1?
If so, there is no need if the equipment is suitable for the intended position.

Only you can answer these questions, so make an informed decision, based on your training, experience, and reference to BS7671, as to whether the equipment is in a suitable position.

and the most important fact concerning that statement is ??.............



yep , the original install would have been designed to 16th ed regs , but will now have to finished to 17th.

i'd be very reluctant to agree to finish work done to an old spec , all sorts of unexpected probs will crop up.
bathroom zones being 1 of them.
