What else can I help you with?
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
For a 400 Amp service with 500 MCM conductors, the minimum size grounding electrode conductor required would be 3/0 AWG copper or 250 kcmil aluminum based on the NEC Table 250.66.
Have 30 amp double pole need 15 amp 120v?
Remove the 30 amp double pole breaker and install at least one single pole 15 amp breaker. It is best if the other slot is not left open so if you have another single pole breaker of any size install it in the 2nd spot so it isn't open when you replace the cover on the panel. For your 15 amp circuit you need #14 gauge copper wire or larger with a hot, neutral, and ground. Your 30 amp circuit was probably wired with #10 gauge conductors. These will probably work on your 15 amp circuit but it may be difficult to connect #10 conductors to devices.
What size ground wire is need for a 30 amp circuit?
On a 30 amp circuit, you would use a #10 copper ground. The ground never has to be larger than the ungrounded conductors.
What size in a 90 amp 220 volt circuit?
A 90 amp 220 volt circuit would typically require a wire size of at least 4 AWG (American Wire Gauge) for copper conductors or 2 AWG for aluminum conductors to safely handle the current without overheating. It is important to consult with a qualified electrician to ensure proper wiring size and installation according to local electrical codes.
How much loss from power pole to 200 amp breaker box then off 400 feet then split at a pump house then another 30 feet to a 100 amp breaker box?
For an accurate calculation it will be necessary to know what the size of breaker exists in the pump house and what size conductors are used. Power loss is measured using actual amps required, not size of the circuit involved. But the size of circuit (breaker size) can be used. Voltage must also be known.
What is the appropriate wire size for a 240V 40 amp circuit?
For a 240V 40 amp circuit, the appropriate wire size would be 8 AWG (American Wire Gauge) for copper conductors or 6 AWG for aluminum conductors.
What is the appropriate wire size for a 220V 20 amp circuit?
For a 220V 20 amp circuit, the appropriate wire size is typically 10 AWG (American Wire Gauge) for copper conductors.
What is the appropriate wire size for a 240 volt 40 amp circuit?
For a 240 volt 40 amp circuit, the appropriate wire size is typically 8 AWG (American Wire Gauge) for copper conductors.
What information can I find in the 400 amp wire size chart?
In a 400 amp wire size chart, you can find information about the appropriate wire size to use for a 400 amp electrical circuit. This includes details such as the gauge of the wire, the maximum current capacity it can handle, and the type of insulation required for safety and efficiency.
What size wire for 400 amp distribution panel?
For a distribution panel rated at 400 amps parallel runs of 3/0 conductors will do the job.
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
For a 400 Amp service with 500 MCM conductors, the minimum size grounding electrode conductor required would be 3/0 AWG copper or 250 kcmil aluminum based on the NEC Table 250.66.
What is the appropriate wire size for a 20 amp circuit?
The appropriate wire size for a 20 amp circuit is typically 12-gauge wire.
What is the appropriate wire size for a 25 amp circuit?
For a 25 amp circuit, the appropriate wire size is typically 10 gauge wire.
What is the appropriate wire size for a 30 amp circuit?
The appropriate wire size for a 30 amp circuit is typically 10 gauge wire.
What is the appropriate wire size for a 50 amp circuit?
The appropriate wire size for a 50 amp circuit is typically 6-gauge wire.
What is the recommended wire size for a 30 amp circuit?
The recommended wire size for a 30 amp circuit is typically 10 gauge wire.
What is the recommended wire size for a 60 amp circuit?
The recommended wire size for a 60 amp circuit is typically 6-gauge wire.
