# Question: What Size Breaker Do I Need For A 10000 Watt Heater?

## Can a 240V heater run on 120V?

Specifically, a 240-volt, 2,000-watt heater will use up 8.3 amperes of current but a 120-volt, 2,000-watt device eats up 16.6 amps.

Installing a 240-volt heater on a 120-volt circuit is not as big a safety risk, but you will notice that your heater will fail to work most times..

## Is a 240V heater more efficient than 120V?

There is no difference in efficiency in our heaters between 120V and 240V (or any other voltage). The reason why 240V is advantageous for appliances and heaters in a home has to do with amperage. … It also requires less wiring and you can fit more heaters on a 240V circuit than you can on a 120V circuit.

## What size breaker do I need for a 15000 watt heater?

If no MCA value, the convert KW to amps at the supplied voltage and phase. If this is 240V single phase, then the amps would be 15000/240 = 62.5A. You are required to treat this as a continuous load, so ampacity requirement is 62.5*1.25 = 78.1A which means an 80A circuit breaker.

## Can a 60 amp breaker feed a 100 amp sub panel?

You can feed a 100 Amp panel with a 60 Amp breaker. Keep in mind that the sub panel needs to be rated above the breaker size.

## Is a double-pole 30-amp breaker 60 amps?

Single-pole breakers are rated for 120 volts and 15 or 20 amps. … The breakers themselves are relatively narrow and occupy a single slot in the home’s breaker box. Double-pole breakers, on the other hand, are typically rated for 20 to 60 amps and supply 240-volt power to large appliances, like electric dryers and ranges.

## How do you wire a double-pole 30 amp breaker?

Installing a 30-Amp Double-Pole Breaker The cable powering the circuit should be securely clamped to the access port. After you strip an inch of insulation from each of the wires in the cable, connect the white wire to an available lug on the neutral bus in the panel and the ground wire to the ground bus.

## How many amps does a 15 KW heat strip pull?

Most air handlers with 15 KW of strip heat. Can often use a 60 amp and 30 amp circuit. The 30 amp has the blower and 1-5KW heater, the 60 amp has the other 10 KW of strip heat.

## How many amps does a 10kw heater pull?

50 ampsA 10kw heat strip pulls 50 amps. 10kw thermal bands are often 9.6 kw. Fixed space heating equipment are assumed to have a continuous charge, so without any other charge considered, there are 9,6240 x 1,25 or 50 amps.

## What happens if you plug a 120V appliance into a 240V outlet?

If you plug an 110V appliance in 220V outlet (same as 120v to 230v, 240v) you can only hope that some protection device disconnects the power to the appliance. … It is current that is your enemy, a piece wire that is warm at 110V (120v) will turn into a fuse at 220V (230v, 240v), all other things being equal.

## What size breaker do I need for a 15 kw heater?

What size breaker do I need for a 1500 watt heater? A 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps.

## How many amps can a 30 amp double-pole breaker handle?

30 amp capacity. Safe maximum: 30 x 80% = 24 amps. 120 volt 20 amp outlet can be installed on 20 amp breaker, but not 15 amp breaker/ use 12 ga wire.

## Can a furnace be on a 15 amp breaker?

The Wire is fine, And the breaker is fine also. Do not sweat it, You can install a 15 amp breaker if it would make you feel better.

## What size breaker should a furnace be on?

The size of a breaker is determined by the amp draw. The exact amps an electric furnace requires is solely based on the size of the furnace and its performance capabilities; however, typically electric furnaces require a draw between 60 and 80 amps.

## What size breaker do I need for a 240 volt heater?

Adding a 240-volt baseboard heater usually requires a new 20- or 30-amp double-pole circuit breaker and new circuit wiring to supply one or more heater units.

## What size breaker do I need for a 10kw furnace?

A 10 KW load at 240 volt will result in 41.67 amp load. Your wire and breaker should be sized at 1.25% of 41.67A = 52A . This would require a 60 amp breaker.

## How do I know if my thermostat is 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.

## Should a furnace be on its own breaker?

According to building codes, a furnace must be supplied by a dedicated circuit, meaning the circuit cannot supply power to anything other than the furnace. This circuit is served by its own circuit breaker in the breaker box (properly called the main service panel).
