A #8 copper conductor with an insulation factor from 75 to 90 degrees C is rated at 45 amps.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

What size wire for a 40 amp breaker to a welder?
A #8 aluminium wire with an insulation factor of 90 degrees C is rated at 45 amps.
Can you use 40 amp breaker for your lights and plug ins?
If you are referring to house wiring then the answer is no. A breaker protects the wire size that is connected to the breaker. In home wiring most homes are wired with a #14 wire which is rated at 15 amps. That is why the wire is protected by a 15 amp breaker. The correct wire size to connect to a 40 amp breaker is a #8. This size wire is too large to connect to receptacles an light fixture terminals.
What size wire do you need to run a 240V plug for a dryer?
the size of the wire that you need to run depends on the the amperage of the device/appliance you'll be hooking up to that line. Use #12 wire for 20 amp, #10 for 30 amp, #8 wire for 40 amps and #6 for 50 amps. Hope that helps.
What size wire cable and fuse for a 9.8KW shower?
7.2kW shower = 32 Amp fuse = 6 mm2 cable size7.5kW shower = 40 Amp fuse = 10 mm2 cable size8.5kW shower = 40 Amp fuse = 10 mm2 cable size9.5kW shower = 40/45 Amp fuse = 10 mm2 cable size10.5kW shower = 45 Amp fuse = 16mm2 cable size
What size wire for a 40 amp breaker?
A 40 amp breaker is used in conjunction with AWG # 8 copper wire. The black and red wires are connected to the breaker. The ground wire is connected to the ground bar and the white wire is connected to the neutral bar.
What is the amp size of a 8 wire?
40 amp
What size wire for 40 amp?
AWG # 8 copper.
What wire size will carry a 40 amp load?
AWG # 8
What size wire in a 40 amp 12 volt circuit?
Use 8 gauge wire.
Can a 40 amp breaker not a 4 amp breaker be used to replace a 35 amp breaker for ac unit?
Depends on the size of the wire going to the A/C. If the wire is AWG #10 you cannot install a 40 amp breaker. If the wire is AWG #8 you can.
Is it ok to exchange a 20 amp breaker with a 40 amp breaker?
No. The 20 amp breaker is probably protecting a #12 wire. Connecting a 40 amp breaker to the 20 amp #12 wire would seriously overload the #12 wire. This means that if the load increased to a full 40 amps the insulation on the smaller size wire would most likely melt off and the wire could short out.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker

What size wire for 28 amps?
Minimum size is 10 gauge with a 30 amp breaker. To be safe I would install an 8 gauge with a 40 amp breaker.
How do you choose the right fuse for the job?
The correct size fuse needed is based on the size wire used in the circuit. The size wire needed is based on the load that will be applied to the circuit. 1. AWG 14/2 wire = 15 amp fuse 2. AWG 12/2 wire = 20 amp fuse 3. AWG 10/2 wire = 30 amp fuse 4. AWG 8/2 wire = 40 amp fuse
Can aluminum 600v wire work a 40 amp breaker?
Wire size is rated by Amperes of current. You did not mention the wire size of the aluminum wire, so there is no way to answer your question. The voltage rating is more a rating of how good the insulation around the wire is.
