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.

Why does the primary side of a step down transformer burn out and not the secondary of a 480V to 240V transformer?

Sounds like the wrong size fuse protection was used. The transformer should be protected to its kva capacity.


What size wire should be used to connect a dryer to electrical panel?

That depends on the dryer. Some have natural gas capabilties and use a standard 120V outlet (20 amp dedicated circuit). Others operate strictly off of electricity and use a 230V power source. These use a somewhat standard dryer outlet that conforms to the plug from the appliance, and are usually (but not always) 30 amps. In the case of the former you would use a 12 gauge wire with 2 conductors (hot and neutral) and a ground. The latter would use a 10 gauge wire with 3 conductors (2 hot wires and a neutral) and a ground. Always refer to the appliance specs to determine how the appliance should be wired, and find a qualified person to install these outlets if they don't exist.


What are the standard size circuit breaker amperages?

In North America the standard sizes for breakers are 15, 20, 30, and 40 amps. The 15 amp size breaker is used in general circuit wiring. The 20 amp size breaker is used for dedicated appliance receptacles, hot water tank and baseboard heating. The 30 amp size breaker is used for a clothes dryer. The 40 amp size breaker is used for the electric range.

Does an air conditioner need special voltage?

Yes, air conditioners often require a specific voltage for optimal performance. Most residential units operate on standard voltages like 120V or 240V, depending on their size and type. It's essential to check the manufacturer's specifications to ensure that your electrical system can support the voltage required for the air conditioner you intend to install. Using the wrong voltage can lead to inefficiency or damage to the unit.

Is there a conversion plug allowing a 3 prong 240V dryer outlet to be used to power a table saw with a 240V volt 3 hp motor when the dryer is unplugged and not in use?

The correct answer to your question will depend on the exact locations used for the present clothes dryer and the planned powered table saw unit and also its power rating in (watts) compared to the dryer. The reason you need to know this for a very important technical reason: compared to the dryer the saw would probably take a different load current and would therefore need a different sized breaker on the main panel and a separate branch circuit cable having a different wiring size as well as a different sized outlet. 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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


Can you plug a 220 dryer in an 220 aircondition plug?

Probably not, the pin configuration of a 30A dryer plug should be different from a 15 or 20A A/C plug. The demand draw of a dryer is higher than that a A/C unit and would trip the 15 or 20A breaker. By putting a bigger breaker on the A/C circuit would not be a good idea either because the wire size to the A/C plug would then be under sized.

How can you convert a 240V clothes dryer to 120V?

Hire an electrician to install for you a 240 line. I agree with Tim. You need a dedicated circuit for a dryer. The wiring is larger and you cannot use the 12/2 wiring that is already there. You need a home run from the dryer to the electricl panel. You need an electrican.
