Good feedback. I'll note that we haven't seen any issues with the Eaton
60A, but we decided to go with Square D because it is robust and cost
effective.

Hi All,
I thought I would follow up to report that I swapped out the old GE 60A
switch with a SQD one, and there have been no blown fuses since!
Cheers,

Trust me when I tell you that all of the line side conductors and taps are
likely fine. It is unequivocally the switch contacts that are the issue.
That said, I usually replace the conductors when there is any indication of
overheating near the terminals. I have seen discolored copper, but it
It is always the left fuse! Thanks all for the pointers. I'll double check
the monitoring, but am thinking that I will be replacing the switch with a
SQD, and replacing the taps and AC wires as well while I'm at it.
Cheers,
Dave

I should also mention that it has nothing to do with ambient heat. This has
occured in all seasons and with disconnects in direct sunlight on a south
wall and disconnects in air conditioned garages.
It's just a garbage product. We switched to Square D for 60A D222NRB
fusible disconnects and are
It's the disconnect. We had dozens of this subpar disconnect design fail on
Enphase systems. The 2 Pole has the same issue.
GE gave us some nonsense answer that it's General Duty and not designed for
continuous high power. Even 40A combined Enphase systems will blow a 60A
fuse.

HI Dave,
Which exact fuses do they have installed?
I’m guessing they are blowing due to not being constant load rated fuses and
summer higher temps.

Hi All,
I am servicing a system that keeps blowing fuses on the AC side, although it
appears that everything is sized correctly. It is a SolarEdge SE11400A-US
inverter.
Max continuous output current is 47.5A x 1.25 = 59.4A. There is a GE
TG3222R
60A AC disconnect, and it is wired up with #6
