What size wire should I use for a 20 amp circuit?

A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.

Can you use 14 gauge wire on a 20 amp breaker?

NEC 240.4(D)(3) states that 14 AWG must be protected at 15A. You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. … Just use the side terminals.

How many amps can 6 3 wire carry?

6/3 is normally protected with a 60-amp breaker. Since there are no 55-amp breakers, code allows you to round up to the next larger standard size.

What size wire is good for 60 amps?

That would be 4-gauge wire. In practice, however, it’s common to wire 60-amp breakers with 6-gauge, 3-conductor wire because an appliance that needs a 60-amp breaker seldom draws the full 60 amps. If you’re installing a 60-amp subpanel, however, it’s best to connect it to the main panel with 4-gauge wire.

What size wire do I need for 20 amp 240 volt?

Use 12-gauge wire for a 20-amp circuit, 10-gauge for 30 amps, 8-gauge for 40 amps, and 6-gauge for 50 amps. Check local codes for requirements.

What size wire is good for 100 amps?

When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.

Can 12 gauge wire handle 30 amps?

How do you size a wire?

Wire Sizing Chart and FormulaCalculate the Voltage Drop Index (VDI) using the following formula:VDI = AMPS x FEET ÷ (% VOLT DROP x VOLTAGE)Determine the appropriate wire size from the chart below.

Will a 12 2 wire carry 30 amps?

If you look in the code book, 12 AWG wire is legal to 30 amps if you can run it at 90 degrees C. Which you can’t except for very narrow conditions. The first impediment is terminations (breakers and plugs).

Is a double pole 30 amp breaker 60 amps?

A main breaker is a large-amperage double breaker, same as any double breaker in the breaker box, except it supplies power to each busbar. So your question is like asking if you can draw 60 amps off a 30 amp double breaker … the answer is NO.
