Question: Can I Use A Double Pole Breaker As A Single Pole?

How many amps is a double pole 20 amp breaker?

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..

Can I use a 2 pole breaker for 120v?

In some circumstances a 120V circuit requires a double pole breaker. If 3 wire romex is used as a branch circuit to supply two 120V circuits (Black, Red, and White wire) a two pole breaker must be used so all ungrounded wires in the multi wire branch circuit are disconnected simultaneously.

What is the difference between a single pole breaker and a double pole breaker?

A single pole breaker is typically used with 120-volt circuits, 15-20 amps. … They are constructed with one hot wire and one neutral wire. A double pole breaker is primarily used with a 240-volt circuit, 20-60 amps and consists of two hot wires.

What is a double pole 20 amp breaker used for?

The Square D by Schneider Electric Homeline 20 Amp Two-Pole Circuit Breaker is used for overload and short-circuit protection of your electrical system. This breaker is compatible with Homeline load centers and CSED devices. The ANSI-certified and UL-listed unit is rated for 120/240 VAC and 10,000 AIR.

Can you split a 2 pole breaker?

Re: 2 pole breakers used for 2 single pole circuits If those are actually separate circuits, there is nothing wrong with using double pole breakers for two circuits, just be aware that when one circuit trips its side of the breaker the other side will trip off the circuit on it.

Do I need a single pole or double pole switch?

A single-pole switch controls just one circuit. A double-pole switch controls two separate circuits. A double-pole switch is like two separate single-pole switches that are mechanically operated by the same lever, knob, or button. … A double-throw switch connects an input terminal to one of two output terminals.

How do I know if I need a single pole or double pole thermostat?

If you see two wires coming out of it in the back you have a single pole. If there are four wires, you have a double pole. If you have more than four wires coming out of your thermostat, you most likely have a low voltage one, which would be used to control a central furnace, boiler, or something similar.

Can a 3 pole breaker be used in a 2 pole application?

A 3-pole breaker used in place of a 2-pole breaker on a 3-phase system, is acceptable without the 3-pole breaker being specifically marked.

Can you use a single pole breaker for 220?

In the US, panelboards are designed with alternating phases down each side of the panel. Voltage from each pole to neutral is 120V. Voltage between any two adjacent breakers, on either side of the panel is 240V. 240V requires service from each panelboard bus, so there is no way to get that from a single breaker.

What is the purpose of a 2 pole breaker?

Double-pole breakers have two hot wires that are connected by a single neutral wire. That means if there’s a short circuit on either of the poles’ hot wires, both trip. These breakers can be used to serve two separate 120-volt circuits or they can serve a single 240-volt circuit, such as your central AC’s circuit.

When would you use a double pole switch?

This is typically used to control a circuit from multiple locations in a series of three switches on one circuit. A double pole switch can be used to control light and a fan or 2 lights on separate circuits.

Can you put two wires one breaker?

When it’s NOT a defect: Double tapped wiring is ok if the circuit breaker is designed for two conductors. If a circuit breaker is designed for two conductors, it will say so right on the circuit breaker, and the terminal of the circuit breaker will be designed to hold two conductors in place.
