220V Outlet Voltage
220V Outlet Voltage
(OP)
Let's start by letting you know I'm a mechanical engineer with an electrical question.
My stove recently died. One of the elements in the oven arced. However, nothing on the stove works now.
After checking the fuse panel and not finding a tripped breaker or blown fuse (I also have part of my house on an old style screw in fuse panel) I unplugged the stove and checked the outlet for power. It's a three prong outlet. (Using #1 as the vertical slot at the 6 o'clock position, #2 is at 10 o'clock, and #3 is at 2 0'clock) From #1 to #2 I get 120V. From #1 to #3 I get 40V. From #2 to #3 I get 80V. If I have a blown a fuse on one leg, wouldn't I see 0V on that leg? What could the problem be? Do I have a short somewhere?

RE: 220V Outlet Voltage
I just checked the fuse box and the same voltages apply to the terminals there. 120 to neutral from one leg, 40 from the other, and 80 between them.
RE: 220V Outlet Voltage
Older buildings are grandfathered as far as code and modern practice are concerned. Usually, unless the appliances were changed out for ones with bigger current draw, the wiring is left unchanged, unless the new appliances start popping the fuses on a routine basis.
My parents' house, built in 1926, is definitely NOT wired adequately for servicing modern appliances.

And about an intermittent open. We found a bad fuse on the main block as well as damage to the area around one of the connections for this fuse block. Looks like I need to finally replace the old fuse box.
Thanks for your help.
