So there is a new type of install that I'm seeing here called a UMA (utility meter adapter). It's just what it sounds like, you unplug the meter, plug in the adapter and wire from the load side of the meter to a disconnect, then plug back in the meter.
The first one I saw came off a 100 amp panel with #10 to a disconnect with 100 amp fuses and then #10 to the inverter. I asked why they put in 100 amp fuses and they said that's what the utility required, I told them that they could have just put in a non-fused disconnect as the wires would melt long before the fuses blow.
I keep thinking that this is wrong, but can't really pull anything up, since it even meets the requirements of the feeder tap rule (utility will not allow more than 3' of conductors from the UMA).
Thoughts?
