    Can I backfeed this old Cutler Hammer 100A main panel?

    how long ago did you did you install solar? I would have thought the 120% rule would have let you add a (max) 40A backfed breaker to your existing 200A panel (since 20% of 200 is 40) interesting bit about not allowing a solar connection to a sub-panel... I didn't know that was disallowed. I...

    Can I backfeed this old Cutler Hammer 100A main panel?

    Thanks @AntonLargiader, and @Norcal for identifying the "era" when this thing was built ;) I couldn't remember where I read about drilling your own hole but last night I found it in the Home Depot reviews... I'm not an electrician and I don't know if code prohibits drilling, so I'm hoping it's...

    Can I backfeed this old Cutler Hammer 100A main panel?

    awww **** that's going to be a huge bummer if I can't use a hold down in there... would a CH125RB part not work (if I drill a hole for the screw)? https://www.cooper-electric.com/product/detail/25780/cutler-hammer-eaton-ch125rb Here's a picture with the dead front off... even though it's old...

    Can I backfeed this old Cutler Hammer 100A main panel?

    I would like to backfeed this older Cutler Hammer 100A main panel with a 2.4kW solar system that will be on a shed 25' away, and I'd like to ask if anybody knows what model panel this is, or sees any code issue with backfeeding the solar to it. I can't find much identifying information on the...

    Back-feeding solar to main panel from shed that has 1 circuit

    thanks again everyone, this has been extremely helpful! fwiw I do plan to upgrade to a 200A service, but that's a bigger project because I'm going to move it (and change windows/doors/framing in the process). I want to get this relatively small solar project done first, and possibly before the...

    Back-feeding solar to main panel from shed that has 1 circuit

    jeepxj... i agree about not wanting a line-side connection. but do you mean to say i'd be exceeding the 120% rule with a 2.4kW system (and if so, what calc did i mess up)? or do you mean i'd exceed the 120% rule if somebody increased it to 4.8kW it in the future (which i already know would be...

    Back-feeding solar to main panel from shed that has 1 circuit

    Hey thanks for the quick feedback folks! I do plan to use micro inverters (either 1 per panel or 1 per side with an APSystems model that lets you connect 4 panels to it). And thank you jeepxj... I figured plan B would be to install a sub-panel at the shed and use 4 of the existing wires (2...

    Back-feeding solar to main panel from shed that has 1 circuit

    Hi, I've got a shed about 25' from the main panel/meter which is mounted to my house, and I'd like to mount 8 solar panels on the shed roof (about 2.4kW total). There are 2 sets of 10awg THHN wires (2 black/2 white/2 green) in 3/4 pvc conduit running from the main panel under poured concrete...
