For a 50 Amp circuit, the neutral wire should typically be sized according to the same gauge as the hot wires, which is usually a minimum of 6 AWG copper or 4 AWG aluminum. However, local codes and specific applications may influence the exact sizing. It's always best to consult the National Electrical Code (NEC) and any local regulations or an electrician to determine the appropriate wire size for your specific installation.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
AWG # 3/0 copper.
You will need AWG #3 if it is a short run.
Depends on the size of the circuit which you did not list.
A 12 gauge wire can support a load of approximately 2200 watts.
You need to look at the regulations that apply in your country. If in doubt, use a neutral wire of the same size as the live wire or wires.
For a 30 amp breaker, you will need a wire that is at least 10 gauge in size.
For a 50 amp breaker, you would typically need a 6-gauge wire.
AWG # 3/0 copper.
For a 50 amp breaker, you will need a wire that is at least 6 gauge in size to safely handle the electrical load.
Yes, in a residential 200 amp panel, the neutral wire is typically the same size as the hot wires. This is to ensure that the neutral wire can safely carry the same current as the hot wires and maintain proper balance in the electrical system. Always consult the National Electrical Code or a qualified electrician for specific requirements.
You will need to use #8 wire.
2AWG.
8 AWG is typical.
For a 100-amp service, you will typically need a wire size of 2/0 or 3/0 copper or 4/0 aluminum. It is recommended to consult with a licensed electrician to determine the exact wire size needed for your specific installation.
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
The recommended wire size for a 20 amp breaker is typically 12-gauge wire.
