A #8 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 45 amps.
For a 200 amp service panel to the water meter, it is recommended to use a 4 AWG copper wire or 2 AWG aluminum wire as the ground wire. This will provide sufficient grounding capacity for the service panel and meet code requirements. Be sure to check local electrical codes for specific requirements in your area.
The amp size of a wire is determined by its gauge, not the number of wires. An 8-gauge wire is typically rated for around 40-60 amps, depending on the type and insulation of the wire.
For a 200 amp service with a 60 foot run, it is recommended to use 3/0 AWG copper wire or 250 kcmil aluminum wire to ensure proper voltage drop and capacity for the load. Be sure to consult with local codes and a licensed electrician for specific requirements and installation guidance.
15 and 20 amps for receptacles and lights, and anywhere from 20 to 60 amps for dedicated loads such as water heaters and air conditioning. The fuse size MUST be matched to the load and wire size, you cannot just arbitrarily pick one!
AWG # 8 copper.
A #8 copper conductor with an insulation factor of 75 or 90 degrees C are both rated at 45 amps.
For safety, approximately 6 or 8 mm. A #14 AWG copper wire with an insulation factor of 90 degree C will have a capacity of 15 amps.
A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
The recommended wire size for a 35 amp breaker is typically 8 AWG (American Wire Gauge) for copper wire.
The appropriate wire size for a 40 amp circuit is typically 8 AWG (American Wire Gauge) for copper wire.
# 10 bare copper.
The recommended ground wire size for a 100 amp sub panel installation is typically 8 copper wire.
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.
For a 220 volt circuit with a 40 amp load, the appropriate wire size would be 8 AWG (American Wire Gauge) copper wire.
For a 240 volt 40 amp circuit, the appropriate wire size is typically 8 AWG (American Wire Gauge) for copper conductors.
Ground is sized based on the size of the feeder wire and not the amps of the service! However, for a 600 amp service 1500MCM copper wire is one option (NEC 310.16) ;therefor, ground wire is 3/O copper (NEC 250.66) or another option is a two sets of 350 MCM copper wire then a #2 copper (since the biggest feeder wire is 350MCM).
