Water heater breaker hot

[cwf]

Last weekend we were campednwith other AS for the Texas rally..
while.plugged in tonthe 30Ampnservice the WH breaker got warm then "tripped".

I reset once... worked, but got warm. Upon arriving home and plugging into shore power there are no problems nor overheating.

I cleaned wh tank for good measure.. no noticeable trash came out.

What is your thought on the cause of this thermal?
There were other warm breakers but no problems on home power.

Thanks in advance...

What voltage was at the campground?

It could be that the usage of hot water was less while plugged in at home. Check the screw connection at the breaker and be sure it is tight. Loose connections are a common cause of heat. Also as Overlander63 mentioned if the voltage is unusually low the amperage will be higher and cause overheating.

Also, breakers are quite inexpensive, if in doubt change it out, less than $10 and available at most home centers.

Sorry slow reply.
Appeared voltage good. However, once home and on our current trip there is not the same heat issue. Had to be the campground power was low.

It is interesting tho....the panel does generate some heat. As does my panel at home. Temp runs about 8-10 degrees above ambient at load.

I will monitor properly in the future. Thanks!
