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





Can you put 2 baseboard heaters on the same circuit?

In most all cases, multiple baseboard heaters can be connected together if the total operational amperage does not exceed the wires and circuit breaker’s capacity. If the heater is too large it must be wired on a separate circuit.

How many 120v baseboard heaters can I put on one circuit?

If we have a 120 V circuit, you can only connect one 1,500 W heater, with a net electric power input being only 1,500 W. Note: We can also put one 120 V 1,500 W heater + one 240 V 1,500 W heater on a 20-amp circuit.

How do you wire two baseboard heaters?

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 many amps do baseboard heaters draw?





Manufacturer’s Recommended Heating Needs

Total Area of Room (sq. ft.) Recommended Heater Rating (watts) Electrical Circuit Size Needed (240 volts)
300 2700 15 amps
400 3600 20 amps
500 4500 30 amps
800 7200 40 amps

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 do you wire multiple heating elements?

Quote from the video:
Quote from Youtube video: First i run these two lines through in 20 amps automatic circuit breaker it depends on how many amps your heating element is going to draw from the power.

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.

What size wire do I need for electric baseboard heaters?



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. The standard circuit cable for 20-amp circuits is 12-gauge cable; 30-amp circuits need 10-gauge cable.

Can wires touch baseboard heaters?

Electrical codes typically do not prohibit installing heaters below wall outlets, but most heater manufacturers recommend against it. The concern is that a cord plugged into the outlet will drape down onto the heater.

What size breaker do I need for a 2000 watt heater?

For example, if you have a 2000-watt heater that uses 110-volt power, its amp requirement is 18.18 amps. If you consider the 80% suggested limit of most breakers, you will have to use a higher capacity 25A breaker.

How are baseboard heaters wired?



Wiring baseboard heaters is as simple as adding a 20-amp circuit. Simply run a 12-2 non-metallic sheathed cable from the electrical service panel to the location of the baseboard heater. Since baseboard heaters have a built-in junction box, you won’t have to cut in a junction box to feed it.

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

Re: Baseboard heater 240volt 10/2 wire 30 amp



With a 30amp breaker on a 240 v circuit you should be fine up to a total of 6120 watts so I would imagine you will be fine unless it is a massive heater you are installing.

How many amps does a 2000 watt baseboard heater use?

2000 watt is equivalent to 8.3 Amps.

How many watts can a 30 amp breaker handle?

3,600 watts



The formula is 30 amps X 120 volts = 3,600 watts.

Is a double pole 30 amp breaker 60 amps?

A main breaker is the same as any double breaker in the box, except that it supplies power to each busbar. The answer is no if you want to draw 60 Amps off a 30 Amp double breaker.

What can I run off a 30 amp breaker?

Typically, a 30-amp breaker is designed for heavy-duty appliances like HVACs and water heating systems. Besides, it can only accommodate 30-amp receptacles if it’s a single-outlet circuit breaker. If it’s a multi-outlet device, we can install a 20-amp circuit to protect the #10 conductor.

How many breakers can I put in a 30 amp subpanel?

The amount of current that is required for the connected loads can only be supported by a 30 Amp sub-panel. The maximum quantity of branch circuits can be determined with a load calculation. Two 15amp breakers or one 15amp and one 20amp can be used on a 30amp circuit.

How many double pole breakers can I put in my panel?



A 150-amp panel would allow a maximum of 30 circuit poles, and a 200-amp panel would allow a maximum of 40 circuit poles. For panelboards not manufactured as “lighting & appliance” panelboards, there is no limit to the number of circuit breakers allowed.

Can I run a sub panel off a 30 amp breaker?

Quote from Youtube video: So if you needed a 30 you would want to go no less than a 50. Here. We've got a three wire with a ground number 10 set that is feeding our panel for 30 amps.
