Welcome to Code Corner from Mayfield renewables, today we’re going to talk more about NEC 2020 section 705.11 (A) and (B), where you’ll find the requirements for making PV connections on the supply side. First, when we say “supply-side”, what we’re talking about is the supply side of the main overcurrent device, sometimes referred to as a line side tap, even though they are technically supply-side connections. Trying to use that language consistently is important, and now the code has given us some very good rules on how to make these connections. So let’s jump in and first talk about 705.11(A).

In this edition of our Code Corner series, we’re covering NEC 2020 section 705.11 as it pertains to supply-side connections.

In this edition of Code Corner, Ryan Mayfield overviews 2020 NEC Article 7015.12(B)(3)(6) as it applies to load-side source connections.

It’s time for another installment of Code Corner, where Justine Sanchez and I turn complex regulations related to PV and solar-plus-storage systems into bite-sized overviews. Here, we’ll focus on NEC 2020 Article 705.12(B)(1).

Section 690.12 of the 2020 National Electrical Code (NEC 2020) covers rapid shutdown requirements and represents a vitally important safety requirement for solar PV systems.
