In response to MxSlick's troubleshooting post, I have one that's pretty good too:
The background on this one is at the Building my girlfriend at that time lives in..
The one Superintendant called the electric company I work for complaining there is a " problem with the power to the stove".. (he actually narrowed it down by rolling in another stove and trying that!!)
But anyway, upon our arrival, we shoved our tester in the stove outlet and saw we were getting 120V from each hot slot to neutral and ground but 0V between the hot slots... We also noticed that ALL the plugs and switches in the apartment have been changed, including the split receptacle in the kitchen..
ALL of the lights and outlets in the unit functioned normally.. All showed 120V... At the split in the kitchen, each 1/2 of the receptacle showed 120V but when you went across the "hot" slots you read 0V ( where you should see 240)...
Down in the electrical room at the unit's disco we found on the LINE side 120 to ground on each leg, 240 across the legs.. Normal..... On the LOAD side we found the same 120 to ground, BUT the same 0V from leg to leg...
Across fuse "A" read 0V, but across fuse B read 240V...
Now, it would appear there is an open fuse, which indeed there was BUT there is that weird 120V backfeed and the entire apartment works as if nothing is wrong
( with the exception of the stove)....
The service to this apartment unit originates from a 600A 120 / 240V single phase service.. It comes off the splitter and goes to a 60 A FUSED disconnect, ( fused with --very old-- regular one time fuses) and then from there it goes to the unit where a 12 circuit breaker panel was retrofitted in..
Now:
Can or does anyone want to give a shot at what the problem in this apartment unit is, or where it is, or the sequence of events that happened to cause this condition to happen????
I will try and check in later or tomorrow (tuesday) evening should anyone have the answer ,has questions or wants to know what happened!!!!!
