Wire Size Chart and Maximum Amp Ratings

Electrical current is measured in amps. Each wire size, or wire gauge (AWG), has a maximum current limit that a wire can handle before damage occurs. It is important to pick the correct size of wire so that the wire doesn''t overheat. The number of devices connected to the circuit usually determines how much current will flow through the wire.

What is the process of grounding and bonding a solar PV array?

It also limits the voltage-to-ground that can occur on normally non-current-carrying metal components, ranging from frames and rails to conduit and enclosures. "Bonding and grounding PV systems ensures public safety, as well as the safety of PV installers and field electricians," said Andy Zwit, Codes and Standards Manager at ILSCO.
