A/C Disconnect blows 1 of 2 fuses
On a net metered system with two identical arrays-16 panels 325W ea., one of the two 25amp fuses blows intermittently.
I put an amp clamp on each of the A/C outputs in the disconnect box and they both read up to 35amps. I’m a little confused at the reading vs. the fuse ratings of 25amps. The readings fluctuate anywhere from 10 to 35amps on a partly sunny, cloud moving day.
I don’t understand how the output fuse can blow going to the meter (after the home breaker panel.) Is this a utility issue? All of the connections in the disconnect box are tight including the fuse holders.
Thanks for you thoughts!
