Forgive my ignorance in terminology, I am a computer engineer but not an electrician. The concepts make sense to me, but I don't know all the industry standards and jargon.
I recently had a 240V external outlet installed for an EV. Naturally this needed a GFI. Not coincidentally, my water heater stopped working the day it was installed.
I have before and after pictures of the panel. The water heater was on the 3rd breaker down on the left, the 20A one which is my "2 pole 2-slot" breaker as opposed to the other 2-poles which seem to often take up 4 slots.
Aha, looks like the breaker was moved up for the GFI. (I opened the panel cover and have confirmed this is indeed the breaker for the water heater) And if I'm reading the wiring diagram correctly...
It appears that it's now on pins 9/11 which is one phase, instead of staggering 11/13 which are 2 different phases.
- Was the original configuration legitimate, or is that fundamentally wrong?
- This was done by a licensed electrician. Is this some common mistake or should I be wary of having them come back to fix this?
