Re: [RE-wrenches] Grounding/bonding question for 200A main breaker service disconnect

It looks like there is a bonding screw just below where the bare equipment grounding conductor lands? That bonds that grounding lugs set to the panel enclosure. You can always do a continuity test from point to point to determine if they are bonded. Michael D Nelson MD Electric & Solar, Inc.

Re: [RE-wrenches] micro-inverters

I've had so many Enphase failures it's kind of ridiculous. We install most of our systems near the ocean so corrosion has played a big factor. The newer micro inverters are holding a much better, 215 and 250's. I have learned over the years that SMA makes the best product, and I mostly stick

I have been using buchannon copper crimps with their plastic snap on "wire nuts" for years to splice rooftop wires (enphase or pv wire to string inverter) inside junction boxes or soladecks. Best connection you can have and I've never had one come loose or melt down. Michael D Nelson MD
