Electric water heater worked fine last night. Heard a "pop" and just thought trailer was cooling down after A/C was turned on after traveling in 102 degree heat.
DW went to ahower this morning and had cool water.
15amp breaker was tripped. Reset and tripped again after 15 minutes.
Turned off power switch and flipped on LP water heater.
Any ideas as to why electric water heater is tripping?
