house electrical question

[Jeff Miller]

Sounds haunted.

We need to isolate the source of the problem.

First plug in the cord to the supply, without the plug on the coach.
No trip?

Next turn the two 30a breakers (separate box below the main breaker
panel in an '82) off, and turn the transfer switch to OFF, plug the
cord into the lower 30a (yellow) coach connection.
No trip?

Turn the transfer switch to "30A"
No trip?

Turn off the two main breakers in the main breaker panel (50a
breakers), and turn on the two 30a breakers in the lower panel one
at a time.
No trip?

Turn off all breakers in the main panel, turn on the main breakers
one at a time.
No trip?

Turn on load breakers one at a time, preferrably with AC and other
loads off until you find the one that trips.
No trip?

Turn loads on individually until the offending load is found.

Once you find the part of this sequence that trips the breaker it
will become apparent where the short is. Most likely it is in the
cordset, or between the 30a connection and the main breaker panel
(which includes the transfer switch). BTW, and I apologize if you
already know this, but the 30a position on the transfer switch is
for the two (yellow) separate 30a cords. When using the single (red-
tape) 30a cord you use the 50a setting on the transfer switch.
