Customer called today, complaining of a water heater I installed last year wasn't providing enough hot water.

66 gallon electric, the customer is a new owner of this condo, not the original owner I did lots of work for.

I asked my normal questions, then he told me that yesterday that his main breaker panel tripped the biggest breaker in it, the big one at top which is either a 150 or 200 amp breaker. 4 connected together.

I asked him if there was a loud bang when it happened and he said since it was downstairs and 2 doors away, he doesn't know.

I told him to immediately contact a licensed electrician to find out what is causing his problem in his panel.

I truly believe that this is relative to his water heater, and if the panel is malfunctiong (why else would the main breaker trip) this might be completely relative to the problem at hand.

Wouldn't surprise me if an element or thermostat was damaged as a result at the water heater.

I told him i wouldn't touch it till an electrician corrects the problem at the panel.
