Hey Melinda! Thank you for calling Kings Electric & A/C for your electrical repairs. Today I was called out because you’re having issues with your 30 amp water heater circuit. I looked at your water heater and the one you purchased was for #6 wire 60 amp and you have a #10 wire on a 30amp. I was able to rewire the circuit to the new wire size, I tested all sinks and shower with your tenant for about 15 mins, and the hot water was working and nothing tripped. If you have any questions or concerns, please reach out. Your electrical technician, Xavier
