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.
