What size main breaker do you need to run 10 gauge wire?
The maximum current that is legally allowed to be applied to a # 10 wire is 30 amps. The breaker required to protect this wire will be a 30 amp breaker
What size wire do you need to run to an air conditioner that has a maximum breaker size of 40 amps and a minimum circuit size of 25.3 amps?
Number 10 thnn copper wire.
What is the cable size for 7.5kw slit system air conditioner?
The wire is sized to the maximum overcurrent protection device (Max circuit breaker) ampacity. This is listed on the nameplate of the outdoor condensing unit. Size the wire to match the breaker.
When installing a circuit breaker do you size the breaker to correct wire size or the device its controlling?
The wire!! The breaker is there to protect the wiring not the device plugged into the circuit.
How do you know if the AC breaker matches the AC unit starting demand load?
Read the literature for the ac condensing unit, or the tag on the outside of the unit. Minimum circuit ampacity= minimum breaker, wire and fuse size. Maximum circuit ampacity= the maximum size. Your circuit breaker, wire size and disconnect fuses should all be at or between those 2 numbers.
What is the maximum wire size needed for a typical branch circuit that is protected with a 20-amp circuit breaker?
I think you mean either what is the correct size or minimum wire size needed when a branch circuit is protected by a 20 A breaker. The size is 12 American Wire gauge (AWG). 14 AWG is used for 15 A circuit and 10 AWG for a 30 A breaker. The lower the gauge the larger the cross-section of the wire.
What size breaker is the minimum using number 4 wire?
using number 4 wire what is the maximun size breaker possible
What size breaker does it take to run a outdoor well?
Normally AWG #10 wire on a 30 amp breaker but it really depends on the size of the pump. The pump manufacture will specify the size wire and size breaker needed.
How do you determine wire size?
Most wires are in terms of gauges.
What gauge wire should be used for a 15 amp breaker?
The correct wire size for a 15 amp breaker is a #14 wire.
What size wire do you need to wire a 200 am breaker box?
6
Can you have more than one conductor in a circuit breaker?
No. Each conductor requires its own circuit breaker. Be sure to match the size of the breaker to the size of the wire. Ex.: 15 amp breaker for #14 gauge wire/ 20 amp breaker for #12 hauge wire.
