What Size Wire Do I Need For 800 Amps?

Can I use 18 gauge wire for LED lights?

Now, I personally use a solid core 18 gauge wire for all my lights and would recommend you do the same.

The cost difference between it and smaller cable is essentially negligible, and 18 gauge is about as big as you can go if you still want to be able to fit it into most COB holders or terminals..

What size cable do I need 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.

What size wire do I need for a 30 amp 220v circuit?

Any circuit fused for 30 amps must use a minimum of 10 ga copper or 8 ga alu. Longer runs may require an upgrade of wire size. In your case, use at least 10 copper for your welder regardless how far it is from the breaker panel.

Can 12 gauge wire handle 30 amps?

No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps.

What happens if wire gauge is too big?

using larger wire will not hurt anything or cause any overload. The larger wire will cost more, the pathway or where it has to fit, and the physical size of the connecting means (ie. the size of terminal or clamp it has to fit in), will all be determining factors in just how big is too big.

Can I use 8 gauge wire on a 20 amp circuit?

You can usually fit 10 AWG wire under the screw; 8 AWG usually won’t fit. … Whereas 12 AWG is rated for 20 amps and 8 AWG is rated for 40 amps under normal conditions, a circuit wired with 12 AWG could drop below 110 volts at the end of a several hundred foot run when loaded to capacity.

How do I calculate what size wire I need?

Divide the voltage running through the cable by your target current. If, for instance, 120 volts will act on the cable, and you want 30 amps to run through it: 120 / 30 = 4. This is your target resistance, measured in ohms. Multiply the cable’s length by its material’s resistivity.

What size wire do I need for 10 amps?

For a maximum of 10 amps, you’ll need a wire gauge of 16.

What size wire is needed for a 20 amp 240 volt circuit?

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.

Can 10 gauge wire handle 50 amps?

For no more than 3 current-carrying (copper) conductors in a conduit/raceway, you’d need a minimum of #8 AWG and depending on the ambient temperature around the conductor, #6 AWG. No. … 10 AWG coper wire is rated for 30 Amps in most installations. 50 Amps calls for 6 AWG or 8 AWG high temperature cable.

What size wire do I need 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.
