Some common electrical requirements for major appliances


**Always check local electrical codes and the use/care manual for your appliance.**


- The polarity for the power wires is important. If the plug outlet is wires backwards.... things like spark modals in gas ranges can fail, you can receive a possible shock trying to simply replace a light bulb.

- Ground plug must never be broken off!! where a standard two-prong wall receptacle is encountered, it is the personal responsibility and obligation of the customer to have it replaced with a properly grounded three-prong wall receptacle. The ground is a safety in case of a short.

Gas range - 110 -120 volt, 60 hertz, properly grounded branch circuit protected by a 20 amp circuit breaker or fuse. Must be properly grounded and polarized. #12/3 wire is a must .

Automatic Washing Machine - 110 - 120 volt, 60 hertz 20 amp circuit breaker or fused electrical supply line. Power cord must be connected to a properly grounded and polarized outlet. Because of water conditions found in a laundry room, a GFI ( ground fault interrupter ) outlet must be used. #12/3 wire is a must .

Microwave - 110 - 120 volt, 60 hertz, properly grounded circuit protected by a 20 amp circuit breaker or fuse. #12/3 wire is a must. A separate (dedicated ) circuit serving this appliance is required..

Dishwasher - 110 - 120 volt, 60 hertz, properly grounded circuit protected by a 20 amp breaker or fuse #12/3 wire is a must. A separate (dedicated ) circuit serving this appliance is a must.

Refrigerator - 110 - 120 volt, 60 hertz, properly grounded circuit protected by a 20 amp circuit breaker or fuse. #12/3 wire is a must. A separate (dedicated ) circuit serving this appliance is a must.

Gas Dryer - 110 - 120 volt, 60 hertz, properly grounded circuit protected by a 20 amp circuit breaker or fuse. #12/3 is a must.

Electric Dryer - 220 - 240 volt, 60 hertz, properly grounded circuit with 30 amp breaker or fuse protection. #10 gauge wire is preferred.

Electric Range - 220 - 240 volt, 60 hertz, properly grounded circuit with 40 amp breaker or fuse protection with #8 gauge wire. With a 50 amp breaker, # 6 gauge wire is required.

All 110-120 volt appliances must be on a dedicated line. This means nothing else on the same line or plug.

208 volt AC- only a 5% voltage variation is acceptable
220-240 volt AC – 10 % voltage variation is acceptable

All 220-240 volt circuits today are a 4 wire circuit. Red, power...black, power...white, neutral...green or bare, ground.

please revise....
 

Some of your information is not correct. Please check your information against the n.e.c. book and see. 12-3 I think you mean 12-2 w/grnd, and not all appliances are required to be on a dedicated circuit. Just dont want anyone to be mislead. Welcome, and good luck....

"Always Check Your Local Electrical Code"
 

As stated in the post. These are the requirements here in Suffolk County, Long Island, New York in which I hold a "Restricted Electricians License" which is required for HVAC/R and Appliance Service as well as "Appliance Repair License". :)

Hello IceHouse:
Thank you for the heads-up. When we need to do work in your area we will observe the new requirements.
