A 750 watt heater at 240 volts draws 3.15 amps so a 2 pole 15 breaker with 14/2 wire would be fine

### Try to hook up my welding to breaker panel how many breaker do I need and what size

Typically a welder is 240v requiring a Double pole breaker, the size would depend on the equipment amps or watts?
30 amps X 240 volts = 7200 Watts

### I have 110 volts n each leg but not 220 across both why??

In a traditional North American residential electrical panel (120/240 volt, single phase), installing a single width or single pole circuit breaker, you would expect to read 120 volts from the breaker terminal screw to either ground or neutral. A double width or double pole breaker would provide 120 volts from either of the breaker terminal screws to ground or neutral AND it will provide 240 volts BETWEEN the TWO breaker terminals.

A single-width circuit breaker case that contains two handles is NOT a two pole circuit breaker (these are called "tandem" or "1/2 size" breakers). This is because a single width breaker engages only one "line" in the panel. A double width breaker will engage 2 "lines" as a triple width breaker would engage 3 "lines" of a 3 phase panel. A single wide breaker can not physically engage more than 1 "line" so it will never be able to pass 240 volts.

You must install a double width / double pole breaker to safely supply a 240 volt circuit / device.

### I need to know fuses box

Copy following link to see basic circuit breaker box.

It appears you are connecting home automation to to breaker box.
Remove one wire from each circuit breaker. Connect this wire to relay. Then run new wire from relay to circuit breaker.
When the relay turns ON, then that will complete circuit to each circuit.
This will work for 240 volt or 120 volt or 277 volt single-phase split phase..

### I have installed a Dimplex 1500watt heater. I used a double 15amp breaker and 14/2 wire (I know should've used 12 guage but changed plans post construction and was told 14 would be fine). There is...

A number 12 copper supply cable at the voltage is overkill for this load.

Ohm's Law states: Watts = Volts x Amps. To find Amps: Amps = Watts / Volts. This is 1500W / 240V = 6.25 Amps. Since the max continuous load for a 14 copper is 12 Amps, this size wire is the correct size.

Check to make sure the heater is in fact a 240 volt type, as if it is a 120 volt type, you are likely instantly burning out the heating element. If it is indeed a 120 volt heater, you will need to connect to a single pole 15 amp breaker and place the other wire that was on the breaker to neutral to provide the correct voltage. The load will still be 1500W, but at half the voltage, the current will double to 12.5 amps, and may cause the circuit breaker to trip after a while.

I hope this helps & good luck.

### I have a electric dryer Model WED5810SW0 THAT I WAS TOLD I COULD CONVERT TO 120V from 240v is this true and if so how do i do this?

If you consider doing this the first thing is SHUT THE MAIN BREAKER OFF. Use an auxiliary light source to see when working in a dead panel. Always keep in mind an ARC FLASH ACROSS HOT MAINS HAS ENOUGH HEAT TO PEAL THE SKIN OFF OF YOU. Before an explanation of how to do it you should keep in mind that this is for a single receptacle only. If any other receptacles are on the same circuit they will also be changed to 240 volt receptacles and if you plug any 120 volt device into them, the 120 volt device will be destroyed. That said OK, any 120 volt outlet can be changed to 240 volt by removing the 120 volt circuits neutral, re identifying the white wire with red or black phase tape and connecting it to a new 2 pole 15 amp breaker. The maximum that this circuit will now load up to is, on #14 wire at 80% = 12 amps at 240 volts. The 120V receptacle must be changed to a 15A - 240V receptacle so that 120 volt devices can not be plugged into it. Never use 2 single pole breakers together because code requires that on a fault trip both legs of the 240V circuit must be disconnected simultaneously.

Voltage converter buying guide. Voltage Transformer Buying guide.Voltage converters also known as voltage transformers are devices that convert foreign electricity to power devices from different parts of the world. A step down voltage converter is a 220 to 110 volts converter. A step up converter is a 110 volts to 220 volts converter. Our 2-way converters are voltage transformers that convert power from both 220 to 110 volts and 110 to 220 volts. They also work with 100 volts, 110 volts, 120 volts, 220 volts and 240 volts. This model is a 2 way voltage converter / voltage transformer available in many different sizes including 100 watts, 200 watts, 300 watts, 500 watts, 750 watts, 1000 watts, 1500 watts, 2000 watts, 3000 watts and 5000 watts.

### When specs say circuit requirement is 40, do they mean the breaker size?

What are you wiring?
Does it seem realistic that you need 40 Amp capacity?

40 Amp circuit breaker is usually 240 Volt and it goes to heat pump, double oven, or some heavy equipment. 40 amp breaker uses 8 gauge wire.

You can figure a circuit with the formula V x A = Watt
If your VA is 7500 Watts and voltage is 240, then Amps is 31.25

### WHAT SIZE BREAKER IS NEEDED FOR 240 VOLT ELECTRIC BASEBOARD HEATE

If there is a 15 amp breaker on this circuit now. Then I would assume the the wire to this breaker is only capable of handling that size and NOTHING larger. There are to many variables. You need to know the maximum amp draw rating of the device. The wire size going back to the service entrance (fuse box). You will also need to know the total power draw of the service entrance to determine if the box can handle the total load. Are there any other branches off of this circuit? I suggest that you get advice from an electrician. If you overload the circuit, you may think everything is ok. But you can cause a major problem. I do not think that you want to take the chance of overloading a circuit. This can cause a fire and or death. Have this inspected by a professional. If you insist on doing it yourself.... contact your local building inspector for guidance.

### Basboard heater installation

if the heater is 120 volt or 240 volt its really pretty easy. at either end is a cover. remove the cover and you'll see a wirenut or maybe just two wires. one side has an integral thermostat. connect your supply to the two wires on the thermostat. connect the other end in your breaker box with the appropriate sized circuit breaker. wire size feeding it will depend on its current draw. how many watts is the heater? 1500 watts will draw 6.25 amps at 240 volts so you can use 14 ga wire. 2000 watts will draw 8.3 at 240 volts - so 14 ga is still ok. 2500 watts at 240 draws 10.41 amps. 3000 watts draws 12.5 amps at this stage I'd use 12 gauge on a 20 amp breaker.
