Electric Work - Grounding and 20amp breakers

The #14 is an issue on a 20 amp circuit.
I am not an electrician but I think a quick fix for that may be to install a 15 amp circuit breaker and see what happens. It might just hold and if it doesn't then there are wiring problems.

In the past couple years I sold 2 houses and bought one, so I have a lot of recent experience with inspectors.
None of the three would have noticed mixed wiring, and I doubt any would have seen the bad grounding.

I am not saying they are worthless (one did notice that a retaining wall was possibly failing, which I missed, so he saved me $5,000) but to expect they will find significant problems is fantasy.

Excellent solution; it will work 90% of the time. For the mixed wiring... If the breaker trips, then you need to fix that circuit. If it doesn't, you are good. Now of course code requires some circuits to be 20a, but in the short term that doesn't matter.

AFCI detect arcs; such as when you yank a plug out while the heater is on. It arcs each time, and eventually wrecks the outlet; resulting in the damage you found.
A GFCI detects current that is not returning properly; a leak if you will. It will stop you from getting serious shock off a hot wire.

I don't know what caused your melted outlet, but a AFCI might be the better choice; a shock is usually harmless, but a house fire is rather serious. (Besides a AFCI also sorta works as a GFCI, but not the other way around.)

How does an AFCI "sort of work" like a GFCI? Can you please provide a link to such a breaker?

An AFCI breaker has Class B 30 mA GFI protection built in. Class A life safety GFI protection is 5 mA.

Electric Work - Grounding and 20amp breakers


Thanks for all the thoughts everyone. I don't have a picture of the melted outlet though the electrician took a picture while here. Maybe I should ask him to send it to me for my records. But aside from that do you mean take a picture of the grounding and the breaker box?

The electrician said he wouldn't rework all the wiring in the house but for each 20amp breaker he would locate the outlet that belongs to it and check it for mixed 12/14 wiring and then if it is in fact mixed or if they are both 14's then he'd change the breaker to a 15amp breaker.

ps. the electrician that was here also remarked, as some people in this thread did, that though people get homes inspected it is nearly impossible for a single person (the inspector) to be so expert in every home area that they'd notice the kind of things a single-discipline expert would notice in their area of specialty. It sorta doesn't matter at this point since I just have to do the cleanup and keep the family safe (and figure out how to pay for it all! lol).

Maybe the guy I use was just more thorough since he was formerly a contractor. He caught several issues others would have missed.
