Default Re: 3 vs 4 wire feed to garage

2017 NEC would be the basis for my recommendation that it does not meet current safety standards. I dont care when it was built, wrong is wrong. My job is to point it out not to decide if it will or will not be repaired. I take this position because like Dan we have areas that dont enforce anything code wise.

Are you saying that a 3 wire system is unsafe?

I've approved hundreds of them and would today if Ohio wasn't on the 2017 NEC

The question new inspectors often ask me is WHERE do you stop.


We are not code inspectors, and a 1961 house does NOT meet current building codes in hundreds of ways.


AND if you are somewhere that they are using the 2006 code ....... WHERE do you stop OR where do you start picking & choosing what you're gonna say ......

In Ohio, if you haven't modified your 1961 house it IS code compliant.

Please be careful when you say not up to code!

I think that it's more of a question as to whether or not it's unsafe. Unless a parallel metallic path has been added between the structures IMO it's not unsafe.

The current NEC says it is wrong. Whether anyone wants to update an unsafe condition is up to them, my job stops at pointing it out.

Good point.

Would you report it as not meeting the current code, as a recommended upgrade or both?

It does not say that at all. You need to read Article 90.

The NEC also says that an existing 3 wire feeder can continue to be used. It simply says any new installations need to be 4 wires. It does not call for replacement.

Good point, the NEC explicitly permits the 3 wire feeder to remain.

Quote:
250.32 Buildings or Structures Supplied by a Feeder(s) or Branch Circuit(s).
250.32(B)(1)Exception No. 1: For installations made in compliance with previous editions of this Code that permitted such connection, the grounded conductor run with the supply to the building or structure shall be permitted to serve as the ground-fault return path if all of the following requirements continue to be met:
(1) An equipment grounding conductor is not run with the supply to the building or structure.
(2) There are no continuous metallic paths bonded to the grounding system in each building or structure involved.
(3) Ground-fault protection of equipment has not been installed on the supply side of the feeder(s).
