As promised ! One of the RFC circuits was a bit on the short side so I was bit disappointed on the neutrals, but rather that than crimping and extending. Isn't quite finished, another circuit to go in on athe lhs RCD. and tidying up, but I knew you wanted to see one Chris ! :D

I know you said you had no more to say, but we would all really be grateful if you could answer B.A.S and tell us why this is necessary, how to conduct such a test, and where this test is required in "our" bs7671 regulations. "delighter": could you also elaborate on why safe zones are...

You may not "give a stuff" what recognized bodies such as the NICEIC suggest is their interpretation of the regs (for which they have a significant contribution to creating) . However my point is that such organisations have a wealth of experience, expertise and qualified employees, which, dare...

No you didn't, and I never said you did. Freezers take a good 12 hours or more to defrost to any dangerous level provided you keep the door shut. Cant see any need to leave 300mm of cable behind the board. Ex telecomm engineer too ! I will post my next 17th board, got one end of the...

Sorry can't agree with posts saying its a neat job. Not the worst I have seen, and better than my first attempts at a CU. Sounds patronising I know, but more careful consideration of where cables need to be presented in relation to the desired MCBs would have made for a much neater cabling. As...

I spose the point is that if at some point a water service is in the ground in copper, then the water within it has an "earthy" potential. At any point where copper is used within the equipotial zone, then it becomes conductive and requires bonding.

BAS, once again you are wrapped up in the world of hypothesis. The NICEIC and from what I hear other scheme operators have made it abundantly clear (as far as they are concerned) that "under supervision of a skilled or suitably instructed person" does NOT apply to the vast majority of...

My understanding is that a water supply, even if fed in HEP, contains water, which is conductive, albeit depending on the level of impurity of the water not a particularly good one. If copper is then used after the HEP supply, then it becomes an ECP and must be bonded etc.

.....which is why a main bonding conductor connects the MET to all ECP of that installation such as the gas service pipe and the water service pipe.

Did you phone them and let them know ? As has been pointed out to you 413-02-02 is main bonding. You have become confused between this and supplementary bonding. A boiler does not require supp. bonding. Neither does a radiator, or other ECP or metalwork in a room other than one containing a...

You are wrong. As mentioned that reg is Main Equipotential Bonding, which has nothing to do with special locations, or supplementary bonding, for that matter. Furthermore in (most) domestic situations should be 10 sq . mm, not 4mm, and should be connected back to the MET. Supplementary...

I disagree. TV, under normal operation, is harmless. A cooker, under normal operation involves areas of high temperatures with risk to burns and flame with risks of both burns and fire, and therefore gives rise to hazard under normal operation. Any machine with accessible moving parts would also...

Oh, thanks for clearing that up for me ! :roll:

No, I'm not getting confused at all. Your original point was that an MCB is only suitable as a means of isolation if it can be locked off or is under your control, implying that this is not a suitable means of isolation for a shower. My point was that this is deemed to be suitable means of...

Why not. I need to isolate a shower, for maintainance. I go into the room containing the CU and isolate it by turning off the switch. OPINION: I have seen several suggestions that the cooker switch does not need to be within 2M of the cooker. Again, where are you getting a distance of "...

If you wish to change a ceiling rose, then what ? If you wish to change a socket outlet, then what ? How can you make first make an argument that a device in the consumer unit cannot be used as a means of isolation, and then not give a valid response as to how you would work on a different...

I like loop in at switches. I recently wired two 4 gang switches, all two way circuits loop in at the switch. I used double gang dry lining box on one wall and a regular double metal on the other. With some thought and preparation the cabling was neat and tidy and plenty of room for the choc...

But you are now assuming that ALL MI's state the specific requirement for a DP pull switch located in the bathroom !! FACT: BS7671 does not state or imply that a shower must have a DP isolator installed in the same room, or within easy reach of the shower. OPINION: DP pull cord switches...
