120 V120 V and allow a range of 114 V to 126 V (RMS) (−5% to +5%). Historically 110 V, 115 V and 117 V have been used at different times and places in North America.

How do you know what voltage to use?

If it uses an AC-to-DC converter, look at the label on the converter for the voltage and current. If it’s battery powered, multiply the number of batteries used by the battery voltage, which should be marked on the battery. The common, household alkaline battery is rated at 1.5volts.

Which voltage is suitable for household use?

110 Volt 15 Amp
This is the most basic outlet, and it is ideal for most of your electronic needs, such as microwaves, TVs, and small ACs.

Can I plug a 240V into 220V?

Yes, any device that is classified in 240 volts and can be used in a 220V socket. If the rated voltage is 240 volts, the boxes can have a power supply of 208V, 220V or 240V.

How many volts is a house current?

It is 220 volts.

How much current is required for a house?

Most homes require an electrical service of at least 100 amps. This is also the minimum panel amperage required by the National Electrical Code (NEC). A 100-amp service panel will typically provide enough power for a medium-sized home that includes several 240-volt appliances and central air-conditioning.

What voltage is a standard outlet?

120 volts

Domestic electrical outlets supply 120 volts in North America and 220-240 volts in Europe, with most nations having outlets supplying voltages similar to one of those two values.

What is my local main voltage?

Electric service providers supply 240 volts of electricity to your home, but this does not mean the voltage remains constant. The voltage can fluctuate between 210 and 250 volts from time to time, depending on how the loads flow through the provider’s power stations and switching facilities.

Is my house 120V or 240V?

Turn off the power to your thermostat before checking the wiring as high voltages can be dangerous and even fatal. You can also look into the gang box of your existing thermostat. If you have black and white wires you likely have 120V. If you have black and red wires you likely have 240V.

How many amps does a fridge use?

According to the United States Department of Energy, refrigerators have an average wattage of 725 watts, which, at 120 volts, computes to an amperage of 6.04 amps.

How many amps is a normal outlet?


The most common electrical outlets are 15-amp duplex receptacles — 15-amp outlets are designed to accept standard plugs for most small appliances and lamps. If you want to replace an outlet, simply turn off the power to the outlet and remove it.

How much current does a fridge draw?

Ratings of commonly used household appliances

Domestic Portable Appliance Amps Used Watts Used
Fridge (under counter type) 0.75 100
Freezer 0.75 100
Mini Fridge 0.5 100
Fridge Freezer (Standard) 1.5 150

Can you plug two refrigerators into the same outlet?

Refrigerators are considered noncontinuous duty loads. Loads that draw current for less than three hours at a time are allowed to be on the same circuit with other noncontinuous loads, as long as the total load does not exceed the circuit breaker rating.

How much voltage does a washing machine use?

120 volt

Washing machines usually cycle for an hour, so that’s 900 W of hourly wattage. Washing machines usually use 120 volt outlets.

How many amps is a washing machine?

A washing machine typically uses between 12 and 15 amps of electricity, while a fridge typically uses about half that amount. This means that you can usually have a washing machine and fridge on the same circuit, but it’s always best to check with an electrician to be sure.

How many amps does a microwave pull?

The microwave ovens consume power at a rate of 650– 1200 watt, which equates to a current of around 10 Amps.

What size breaker should a refrigerator be on?

A 115-volt or 120-volt, individual, properly grounded branch circuit with a 3-prong grounding type receptacle, protected by a 15 or 20 amp circuit breaker or time-delay fuse. Should be on a dedicated circuit.
