4 Frequently Asked Questions about “Photovoltaic panel tap - Shore Power Energy”
What is a line side tap?
Governing Code (s): NEC 705.12 (A), 705.31 A line side tap (or supply side tap) refers to a connection between the meter and main breaker. This is the preferred method of interconnection for solar installers as it is the most straight forward and requires the least amount of calculations.
How do you interconnect a PV system to a utility system?
The National Electric Code allows for a few different ways to interconnect PV systems to utility systems. In two editions of Code Corner, Ryan Mayfield with Mayfield Renewables, explains busbar, load side interconnections in 705.12 (B) (3) (1) and (2), and then supply side connections in 705.11 (C) and (D).
What is a supply side tap?
First, when we say “supply side,” we are talking about 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.
What is a load side tap?
Load side taps are common for residential systems and smaller commercial systems. When designing your solar system, the provider must consider the 120% rule. This rule was established by the National Electrical Code (NEC) to identify how much power can be safely back-fed through the load side of the existing electrical panel.
NEC 705.11 & 705.12
NEC Section 705.11 provides clarity and structure for supply-side PV system interconnections, especially relevant for commercial systems and space-limited panels.
