ReneThe maximum ampacity for 4/0 copper wire is approximately 230 amps when used in a building or residential wiring application. This rating may vary depending on the specific insulation type and local electrical codes, so it's always best to consult with a qualified electrician for accurate information.

What wire size to use for 90 amp load at 480V at 75 feet?
Up to about 100 ft the size of the wire is determined by the max current and not the distance. A 90 amp supply needs #6 wire. <<>> A #2 copper conductor will limit the voltage drop to 3 percent or less when supplying 90 amps for 75 feet on a three phase 480 volt system.
Could you use a 12gauge wire for a 25 amp breaker single pole?
No, a 12-gauge wire is typically rated for a 20 amp circuit. To safely handle a 25 amp breaker, you would need to use a 10-gauge wire. It's important to match the wire gauge to the amperage rating of the breaker to prevent overheating and potential fire hazards.
What wire size should you use with a 30 amp breaker?
No! The minimum wire size allowable is 10 gauge for a 30 amp circuit. Don't risk the chance of an inner wall fire because too small of a wire gauge was used. Never shortcut anything to do with electrical wiring. Never.
Where can you find a 10 amp 125 volt fuse at?
You can find a 10 amp 125 volt fuse at hardware stores, electronic supply stores, home improvement stores, and online retailers such as Amazon or eBay. Make sure to check the specifications of the fuse to ensure it meets your requirements before purchasing.
Can you use 6-3 NM wire and 50 amp breakers and 50 amp range cord for a 40 amp max load range?
No, it is not advisable to use a 50 amp breaker with a 40 amp-rated appliance like a range. You should match the breaker size to the appliance requirements. In this case, you should use a 40 amp breaker, 8-3 NM wire, and a 40 amp range cord for the 40 amp max load range.
