I was just wondering if double-taps were ever within the rules of the NEC. The reason I’m asking is that I, like every good home inspector, call out any double-taps I find and recommend that they be further evaluated by a qualified electrician and/or repaired. Mostly, the double-taps are lighting circuits.
When the electrician checks it out, the feedback I get from the sellers and/or buyers falls into two categories:
The electrician says that it definitely is a violation of the current NEC and should be changed immediately and offers to repair it, etc…
The electrician says that it definitely is a violation of the current NEC, BUT says that since it is original wiring and was done under previous code regulations, it not required to be changed at this time. He does add that if the breaker, at some point, needs to be changed then the double-tap is required to be repaired. He, of course, recommends that it be repaired at this time but does not push the issue.
I, personally, have heard electricians say the same thing about GFCI receptacles in kitchens: they are not required to be changed unless the receptacle needs to be changed, then it must be replaced with a GFCI receptacle or a GFCI breaker installed. They do, of course recommend GFCI’s as a matter of safety.
I live in an area where aluminum wiring was used - Henry Kaiser development in the '70’s. I have heard the same argument regarding the wiring: it should be replaced with copper or properly spliced (Copalum) with copper pigtails, etc… However, it is not required to have every resident in the area do this.
My inspection reports always say I recommend further evaluation of double-taps, etc., by a qualified electrican, and that I recommend installation of GFCI equipment for safety. I do not say it is required to be repaired/replaced by code. Should I be saying that - or more correctly, CAN I be saying that.
Thanks for any replies!
