This table lists the American Wire Gauge (AWG) sizes for copper conductors. In addition to wire size, the table provides values for load (current) carrying capacity, resistance, and maximum frequency. The resistance and skin depth noted are for copper conductors only.

Includes 12, 24, and 120-volt charts and a metric to AWG size conversion table. This is a five percent table which means at these amperage ratings at the listed distances, 5% of the power would be lost to resistance.
MC connectors are specially designed for low contact resistance and good stable connections under a wide range of conditions. MC means "multi-contact." The term "multi-contact" comes from the fact that the connectors have a bunch of little spring loaded gold plated fingers that ensure good contact.
