We'll not quite but anyway, the point made regarding the distance of these cu's from the flat is very relevant with regard to issues of volt drop etc. I would have to agree with Ban on his Switchfuse idea and a local cu, supplied via 16mmsq SWA. This seems like the best solution. Although 16mmsq...

It could be, but i don't fully understand what you are saying. The socket beside the CU which has a freezer plugged into it is likely to be NON - RCD protected so as to maintain supply to the freezer in the event of the RCD tripping. I would not switch this socket over to RCD protection (is this...

No, it is not "good design" to use a clock connector. Such an accessory is, as the name suggests for connecting clocks Full Stop Is a dedicated circuit out of the question (i.e. a drop to the c.u)? Have you completely exhausted the possibility of the socket ring main? RCD protection...

It is 2.5sq SWA Which is rated for 42A in britain (i think). 45A here when burried directly in the grownd.

ignore it, nonsense. It is not essential that the cable is RCD protected and to be honest this is not a major issue in a domestic installation. The ideal solution to your problems however would be the following. A 32A 100Ma RCBO (MCB / RCD combined) fitted to the non - RCD protected side...

the simple answer to your question is yes. 6mmsq is acceptable for a 9.5KW shower, however this is the max. 10sq is NOT required here but for anything significantly above 9.5KW it is.

thats what you should have done in the first place :!:

damp on the brain!! :) My bet is that he connected the neutral to the wrong block in the CU. N/E reversal seems less likely.

I agree, but an RCBO could be fitted alongside the existing board in a 2-module enclosure

IF this shower is 9.5KW then 6mmsq cable will suffice, although it will be running at it's limit of complience. I would reccomend that a 40A RCBO be fitted to the circuit at the board.

i disagree plugwash, why 6A breakers? RCD protection is really not required here and i would advise against it for SON floodlights (if you were to use one) as it may be subject to nusance tripping. As regards not haveing separate circuits entering the same box I made this point already.

What size cable do you intend using. I would use 1.5sq T&E as opposed to 1.0sq and use a 10A MCB. One circuit should suffice. Although I personally, would connect the 500W spot light to a separate 6A MCB. (is this light fed from a switch that also supplies other lights?, if so, all lights...

Exact british reg's i cannot help you with, but this is really a judgement call you have to make yourself. What cable do you wish to cover? If you could provide more info, such af why do you want to do this, it would be a help. The term you used "unacceptable" might be a bit strong :)

3 pages of a nonsense argument on 3-phase motors. I'm afraid I cannot fault FWL in what he is saying although it was a little misleading at times. I have been fitting large (I’m talking industrial, over 100Kw) 3-phase motors for the last 25 years, I have never come across a 3-phase motor...

That's only a Mickey mouse siren. The one on our fire station was replaced last year. "It broke" I brought it home and found it was only a faulty winding (although awkward to repair) It's a 3-phase 305db motor driven siren :) Fancy living beside me!

I'd imagine c.k. is referring to "Emergency Authorisation" codes or P.I.N.'s This is a system in Ireland where a "competent person" (i.e. electrician involved in working with the public, industrial/commercial, some fire services etc.)may call the ESB emergency number in Dublin and authorise...

LISTEN! I agree with you. You are correct. I believe that how you suggest is a suitable way of connecting this fan! I have meerly being trying to show where somebody might be coming from and a reg here which agrees. No matter how much shi*te the entire thing might be.

i do agree with you, as i already said. I was just supplying info as to the situation in ireland which yes (i agree again) is pretty of the wall. But, you do see where this is coming from, suppose the 1.5sq from the shower isolator to the FCU became damaged and the permanent live and the...

Ban, along which others using this forum appears to be touring the world present! :lol: FWL, I think i can see were plug is coming from, as it is labelled "bad practice" in our RECI handbooks and is not permitted in a commercial/industrial installation. (just a piece of info, not casting...

Thanks plugwash :)
