Does Your Kitchen Wiring Have What It Takes To Handle Modern Loads?

Modern kitchens exceed anything people only dreamed about 50 years ago—almost all of the excess is due to electrical appliances and lighting. Double ovens, warming drawers, dual fuel freestanding ranges, gleaming cooktops, range hoods, wine chillers, ice makers, French door refrigerators—those are only a few things today’s cooks have on their wish lists. Throw in 1000-watt microwaves, espresso machines, heavy-duty mixers and food processors and you’re pulling a more power than whole homes once offered a few decades ago.

Building Codes and Shared Circuits

Building codes require separate circuits for high-demand kitchen appliances like electric ranges and dishwashers. Convenience outlets aren’t typically on separate circuits. Several may be on the same one, so using multiple things at once can overload them. Kitchen outlets may also be on circuits shared with other rooms, so their load will factor in as well.

If your kitchen was wired to meet the demands of the 1990s, you need an upgrade to handle 2015 and beyond.

Circuit Wattage

The following table lists typical operating wattages for kitchen appliances. To determine the amount of wattage a circuit can handle, multiply the circuit's amperage by its volts. For instance, a 20-amp, 120-volt circuit can handle 2,400 watts. 240-volt electric ranges and ovens will be on 30-, 40-, or 50-amp circuits, so a 40-amp, 240-volt circuit will handle up to 9600 watts. Also bear in mind that some appliances like refrigerators and dishwashers may require over three times their running wattage to start up, causing additional peak loads on a circuit.

Kitchen Appliance Operating Wattage Kitchen Appliance Operating Wattage
Electric Range Up to 5000 Garbage Disposer Up to 950
Electric Oven 4000-8000 Microwave Oven Up to 1450
Refrigerator, Average 600 Coffee Maker 850
Freezer 500 Toaster 2-slice 1100
Dish Washer - Cool Dry 700 Toaster 4-slice 1650
Dish Washer - Hot Dry 1450 Electric Skillet 1500

Aluminum Wiring and Other Fire Hazards

If your kitchen has aluminum wiring or improper connections, an upgrade is necessary as both dramatically increase the risk of malfunctions and fire hazards. The best way to avoid overloads and dangerous situations is to have a licensed electrician inspect your wiring and advise you before changes are made.
