Default Floating neutral or wiring problem?

If you test between the two hot legs, you should get 240 volts. If you
test from each hot leg to neutral, you should get 120 volts. If you got
120 volts between the two hot legs, you have a dead leg. You need the
check the breaker or fuses feeding that sub panel


All the 15A circuit fuses in the main panel check out ok when I
test-replace them with a new fuse. I get 0.2 Ohms on the large 100A, and
40A fuses so they're fine too. So now I'm thinking maybe it's not a
floating neutral, but rather it could be a dead leg on the phone pole?
Maybe one of the hot legs could have broken on the phone pole from the
swaying tree branches just like the neutral line connector broke last
year.. would that be consistent with these symptoms?


You want to test at the main breaker, preferably with the main turned off.
You have three legs coming in, 2 hot, 1 neutral. With the main breaker in
the off position you should get 240 volts across the 2 hot legs, and 120
volts from each hot leg to neutral. If you don't get 240 across the 2 hot
legs, one of them is dead
