Now I have another conundrum. My neighbor friend is a pool repair guy and he installed a couple of pool heaters at two different residences in which the pool panel originally only had the 6A, 240V pump motor and a 12V, 300W transformer powering the 12V,100W pool light and was fed with a #10-3 NM cable. Now a 38A, 240V pool heater is installed. Both..-same builder, same house. He asked my opinion and of course I said the feeders had to be up-sized to at least #8. So..that is what we agreed to and did..replaced the #10-3 with #8-3. Now his 2P40A QO circuit breaker in the pool panel trips each time the motor is running and the heater kicks on. ?:?
He was actually running the same set up on the #10's for about the previous 48 hours. Now that I upsized the conductors the OCPD decides to trip. ?? All I can think of is that possibly the #10 was absorbing some of the in-rush power?..acting as some sort of 'buffer'? and dissipating it as heat?
