2 wire (plus ground) is all you need for a 240 volt heater provided there is no 120 volt accessories in the heater such as a built in convenience receptacle. If cable is used, the white wire of the 2 wire cable will be a HOT-LEG even though it is white-this is one of the code exceptions. The size of the guage is dependent on the size of the load and other factors. 12 guage will handle up to 1500 watts generally.

How do I determine the voltage of the wall thermostat for an electric baseboard heater.?

There are two different types of thermostats for electric baseboard heaters. Line voltage and low voltage. Connection to a line stat used the source voltage from the distribution panel and operates like a switch. Because the baseboard heater usually is 240 volts the stat breaks both hot inputs. The stat output goes to the baseboard heater. When the stat calls for heat its internal switch closes and applied the 240 volt to the heater. On the side of the stat will be a voltage and current rating that the stat must operate within. The other type of thermostat is used in low voltage installations. Instead of the switch being in the wall like a line stat, there is a low voltage relay mounted in the baseboard heater itself. This relays coil is usually 24 volts AC. An external 24 volt transformer is needed to supply a voltage to this coil. This 24 volt supply is first taken to the low volt stat and an internal low voltage switch is used to energise the coil of the relay in the baseboard heater. The difference between the two stats is very noticeable in that the line stat is very heavily built with strong termination points. The 24 volt stat is very flimsy in comparison as the current it has to handle is only the relay coils current.


How many watts of electric heaters set on low?

The wattage of electric base board heaters does not change because the thermostat is set on low. The wattage is a fixed value on the heater because of its internal resistance element. The thermostat set on low shuts off at a lower temperature than a thermostat that is set on high. It is the time interval that governs the amount of heat that the heater produces when the thermostat calls for heat. Once the room heats up to the temperature that the thermostat is set at, the heater shuts off. The thermostat is just a temperature switch.

Why would one circuit in your house have low voltage but not all of them?

There are several possibilities. You could have a bad breaker that has internal resistance causing a voltage drop. If all the devices on the circuit are low then this is a likely possibility. There could be a loose connection in the electric panel either on the neutral or hot side. This will also effect all devices. If problem is not at all devices there could be a loose connection in a junction box.


Is a lawnmower an internal combustion engine?

If the lawnmower is not electric powered then is is probably operated by an internal combustion engine (petrol or diesel. Oddly enough, very early lawnmowers were steam powered, which means they were examples of external combustion engines.
