Installing 240v light switch

I'm installing a small baseboard heater in a back bedroom, adding it to a V circuit with two heaters already installed in other rooms. I mainly use the two heaters on low when I am away to prevent pipes from freezing. I heat with wood when there. I would like to be able to totally cut off power to the newly added third heater. This bedroom gets closed off when I am away and since the heater has a built in thermostat with lowest setting of 32degrees it will likely come on when the room is closed off.

I don't need or want that No pipes back there. I would like to install a switch to the line before it reaches the heater to simply cut the power to that back bedroom heater when I'm away. Yes, you can do that if the switch is a double pole switch rated for volts or higher and is rated for the current of the heater. The National Electrical Code requires that the switch be rated for the load it serves. This means voltage AND current. There are also line voltage thermostats with a positive OFF position so you wouldn't need the switch.

Whether you use a single pole or double pole switch it will work the same. It is a single phase circuit and it will work either way. However, the Code requires that the switch disconnect all ungrounded conductors. See below. The difference is, with a double pole switch you are breaking the circuit in two places at the same time instead of one. This reduces the amount of pitting on the device contacts.

With a double-break device the contacts will last longer at any given voltage. At volts contact pitting is much higher than at volts. Additionally the National Electrical Code requires that all ungrounded conductors to fixed electric space heating be disconnected:. Means shall be provided to simultaneously disconnect the heater, motor controller s , and supplementary overcurrent protective device s of all fixed electric space-heating equipment from all ungrounded conductors.

C Unit Switch es as Disconnecting Means. In one-family dwellings, the service disconnecting means shall be permitted to be the other disconnecting means. So, a volt circuit would require a two pole switch if it used as a disconnect for the heater. They make 1- and 2-pole switches rated for 20A and 30A, go with what your breaker says.

And those are rated for V. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use. The Plug-In Outlet Tester. This is great to troubleshoot a problem with outlet circuit wiring, is also used by most inspectors to test for power and check the polarity of circuit wiring.

It detects probable improper wiring conditions in standard VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect, Very handy and easy to use.

The Wire Stripper and Wire Cutter. A wire stripping tool used to safely strip electrical wires. This handy tool has multiple uses: The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation. The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets.
