IAS Posted May 15, 2011 Posted May 15, 2011 agree with what you say but the breaker was spare ie it is fitted to the consumer unit but had no cable connected to it,if i was then the 1st person to connect a cable to it then i would be creating a new circuit,i am aware that you can spur from inside a consumer unit from an existing circuit but cant start a new one,just think its madness that i could have piggy backed into another circuit but am not allowed to use the empty breaker terminals a few inches away.sorry if i wasent clear. this was argued on the IET forum by a lot more knowledgeable folk that us - using the fitted breaker does not make a new circuit, it`s there and part of the installation prior to your arrival - therefore the need for notification doesn`t apply. your not supposed to spur from an mcb but obviously you can from a j box outside a consumer unit - now thats madness. You cant get better than using a mcb dedicated to that circuit, spurring off an existing circuit and you can become liable for all thats on that circuit, madness yet again who says your not supposed too?

Like you say, just opinion. Can be equally argued that the circuit in the CU was already in place and that you have simply modified it. The cable is only part of the circuit, not the whole.

IAS Posted May 15, 2011 Posted May 15, 2011 you do realise i wasn't referring to your earlier quote? but to the incorrectly edited one. yes and I was saying you we`re correct.

goodwin Posted June 5, 2011 Posted June 5, 2011 Electrical IEE regs BS7671 are a little confusing sometimes but inshort the person doing the work needs to be suitably qualified and also be deemed a comptent person.Depending on how the spur is installed it could attract a minor works or installation certification.Also the work would probably need RCD protection in some form as req.The work would req testing and the results recorded on the cert.This work would also be notifiable to a regulatindg body NIC EIC or building control.Hope this helps. the legal requirment for any electrical work is to be competent even periodic inspection and testing. everything above is right apart from it prob wounldnt need to notify LABC also NICEIC isnt a regulating body nor is elseca/ECA, napit or bsi, as there isnt one (but we should have one)
9651 Posted June 8, 2011 Posted June 8, 2011 your not supposed to spur from an mcb but obviously you can from a j box outside a consumer unit - now thats madness. You cant get better than using a mcb dedicated to that circuit, spurring off an existing circuit and you can become liable for all thats on that circuit, madness yet again You can take one spur directly off an mcb at the CU http://img705.imageshack.us/img705/7621/lol1ib.jpg
