All 20 amp breakers

[Joshua L. Frederick]

1995 house electrical panel wired all with 12 ga. and 20 amp breakers, no 15 amp breakers for lighting, etc. Are lighting circuits supposed to be 15 amp?

[Robert Meier]

No, there is no requirement to use any 15 amp branch circuits. In some jurisdictions #14 AWG branch circuits are prohibited with #12 AWG conductors being the minimum size.

[David A. Andersen]

It would be nice if they did this more often, less voltage drop issues to deal with.

The Sparkys here don't like this . It would mean work would be harder making their connections . I asked for that in my shop for all my plugs . But man there was a lot of gripping about it .

[John E. Mullarkey]

Dave is right, run #14AWG over 50' and you start to have problems with voltage drop. With all the sensitive consumer electronics about it is starting to become a problem.

[Marc D. Shunk]

A man would be hard pressed to make an argument that voltage drop causes any problems in a residential setting. The tool that home inspectors use to measure this has a HUGE flaw.

Carry on....

Hello again, Mark......welcome back.....maybe only for a while though!~!~! LOL!!

When I wired under a licensed gent in the 1970's, it was required that feeds over 50 feet in houses be #12......somewhere along the line this requirement was dropped......the V drops were insignificant

I understand, but I think you are parroting old wive's tales. That requirement does not appear in NEC that has ever existed.

[David A. Andersen]

I think when we find 93 VAC at a wall outlet without a significant load, there may be an issue involved.

When you don't have the supplied voltage required by the equipment Mfg, this is not an issue?

Also, when I find a voltage drop with one of thoes nifty testers and then find overheated wiring inside the finished wall with Thermal Imaging is of no concern?

Yes, there is a lot of wive's tales around here Mark. However disclaiming the issue with a blanket statement may not be best.

I think that Marc was saying that the NEC has never required voltage drop compensation. He just has a special way of saying it.

So VD compensation is required in Canada?

Does this require a shot? . Who pays, the giver, the receiver?

How much would that be??? LOL

It was but not now in residences....I never worked commercial, etc.

Hello David A. Andersen, I am not picking on you just asking if you have any IR pictures depicting the elevated IR signature of the wiring concealed with in the wall. I understand if there is a load applied to the circuit you may see a elevated temp due to the equipment drawing additional current because of the reduced voltage. The comments you posted just may not have given all of the info I needed to understand it. Thanks I am just trying to learn.
