How many baseboard heaters can I put on a 30 amp circuit?

These three baseboard heaters can be connected to a two-pole 30-amp breaker that is supplying power to the heaters with a two-wire 10-gauge ROMEX® cable-type wire.

How many amps does a 240 volt baseboard heater use?

A 240-volt baseboard heater requires its own dedicated 20-amp or 30-amp 240-volt electrical circuit. A 20-amp circuit can safely provide 3,800 watts of power, while a 30-amp circuit is suitable for up to 5,700 watts.

How many baseboard heaters can you put on a 20-amp circuit?

If you use 240V baseboard heaters, the 20-amp circuit can support a net total of 4,800 W. That’s two 2,000 W baseboard heaters or three 1,500 W baseboard heaters. In short, a 20-amp circuit can handle anywhere from 2,400 W to 4,800 W of baseboard heater electric power input.

How many amps does a 2500 watt baseboard use?

First of all, (assuming U.S. electrical power standards), is the heater being fed by 120 or 240 volt AC? Second, it’s not just the breaker rating, but the wiring as well. At 120 volts, a 2500 watt load (heater) consumes roughly 20 amps. You would need a 30 amp breaker and #10 AWG wiring from the breaker to the heater.

What size breaker do I need for a 2000w baseboard heater?

Assuming 240v baseboard heater. 2,000 w / 240 v = 8.333 – 15A breaker apparently, but more calculations are required. Heating circuit at 80% of max circuit capacity = 12 amps max on a 15A circuit. Heating circuits are considered a continuous load so they should only be loaded to 80% of maximum circuit rating.

Does a baseboard heater need a dedicated circuit?

240-volt baseboard heaters are in need of a dedicated circuit to supply enough power for proper functionality. The general rule of thumb is that baseboard heaters need a 20-amp circuit that requires a 12-gauge wire for either type heater.

How many heaters can you run on a 30 amp breaker?

The number of heaters you can attach to one thermostat also depends on your circuit and wiring
Volts Size of breaker Maximum watts on circuit
240 20 Amp Double Pole 3840
240 30 Amp Double Pole 5760

How many amps does a 1500 watt heater draw?

12.5 Amps
A 1500 watt space heater (on high setting) will draw 12.5 Amps. When a few lights or a television are on the same circuit, the 15 Amp limit is quickly reached and the breaker will trip.

Can I wire a baseboard heater to an electrical outlet?

No. Electric Baseboard heaters are not allowed under outlets. They also are not to be wired to general purpose branch circuits .

How many watts does a baseboard heater use?

Baseboard heaters are available from 400 watts to 2500 watts in increments of about 250 watts. Heating elements are normally rated for 120, 208 and 208/240 volts. 277 volts and higher voltages are available.

Can you wire baseboard heaters in series?

Connecting the heaters in series means that one of the wires from the power source (the thermostat) goes on one end of the first heater, the other end of that first heater is connected to one end of the second heater, and the last end is connected back to the power source.

How do I control multiple electric baseboard heaters?

All heaters must be wired in parallel. You can either do that by connecting each heater to the thermostat directly, or by connecting each heater to the next — just be sure that each heater is connected to the source wires.

How many heaters can you run on a 20 amp circuit?

A 20-amp breaker can support any combination of heaters up to a total of 3,840 watts. For example, using a single thermostat, the breaker could support two 1500-watt heaters or three 1000-watt heaters.

How many amps does a 2000 watt heater draw?

8.3 Amps
2000 watt is equivalent to 8.3 Amps.

What size room will a 1500 watt heater heat?

about 150 square feet
1500 watts will heat spaces up to about 150 square feet and can help you stay warm and toasty in a medium-sized room, office, kitchen, or modest-sized living room.

What size breaker do I need for a 1500 watt baseboard 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. Include the current draw of any other devices on the circuit when calculating the breaker size.

What wire do you use for baseboard heaters?

A 12-gauge wire is typical in many homes, and it is larger than a 14-gauge wire and smaller than a 10-gauge wire. Generally, 10- to 12-gauge wire is what you see in most homes and is what would be used for baseboard heaters.

How many baseboard heaters do I need per room?

Instructions. As a rule of thumb, assume a room requires 10 watts of electric heating per square foot of room. In other words, a 10×10 room (100 square feet) will require 1,000 watts of electric baseboard heating. This heating can be provided by a single baseboard heater mounted on the wall.
