The reason for today’s visit with the customer was an issue with the water heater currently not working and causing a trip on the breaker. When first arrived we were taken to the location of the water heater/furnace room which also housed the panel as well. The location was on the back patio closet where i saw a Challenger panel with original breakers and wiring. I began checking the panel for the correct power down to the water heater and it read 240 volts from the breaker to the end of the wire. When i then tested the wires on the elements for the water heater i saw that the upper element thermostat did not have any power where as the secondary element did. I recommended to the customer that the electric going to the water heater was correct and that the issue was internal on the unit.
