Refrigerator Amp Draw: What You Need to Know

On average, domestic fridges drain around 500 – 750 watts of power. A 750-watt system would need around 6.85 ampere current to operate with only a 110-volt current. The equation for conversion watts to amps is Volts = Amps * Watts. A fridge will use about half of a standard 15-amp circuit’s accessible amperage, and more than the one-third of a 20-amp connection.

The National Electrical Code (NEC) states that throughout normal usage, a circuit can bear only 80 percent of its authorized capacity. Within these conditions, a 15-amp circuit would also have a true overload level of 12 amps. The suggested operating standby capability might only be 5.2 amps, with a 6.8-amp load onto the circuit. Raising the capability to 20 amps will give greater safety factor, but careful measures should still be adopted in order to avoid issues.

A 15-ampere circuit’s remaining power will certainly support an electric opener. Trying to work on the above circuit with an oven or toaster whereas the compressor for the fridge is functioning will probably wind up in a tripped breaker. Any further equipment on the same 15-amp circuit would choose to be precisely designed.

All of this might be highly confusing so you should learn about Amperes, Watts, and Factors that affect consumption of power fridges and house hold appliances.


An “amp”, short for ampere, is a unit of electric current. It is the electromagnetic pressure that flows through an electrical conductor that carries a certain amount of electric current. Moreover, Ampere is used to measure the flow of electricity in a material as an electrical current.

Amperes can be calculated if we have the watts and voltage of a circuit. The formula for Ampere is given as:

Ampere = Watts/Volts


Power could also be a calculation of the rate at which energy travels, and is expressed in watts (W) in electrical systems.

Watts = Volts * Amps
