In fact, it is possible to carry a 2000w 240V load on a 12/2 NM-type motor The cable you see here is a type B cable. A test of its electrical system will not be passed. A 40A breaker will fail as long as the heater is never being pulled at 40 amps, and if someone came along and added load to the heater circuit, it would simply burn out the 12/2 if it was loaded. I could not find a kit that works at 40 amps with #12 or #10. A 35A load would put both of them overhead. In this case, you can drop the breaker to a 240V 20A circuit breaker and the cable and load would both The improper color coding of this 12/2 cable would still prevent it from passing inspection. In the event that the next owner of your house calls an electrician to rewire the house, the electrician will believe the heater is 120V because standard household color coding is as follows There are three wires in the circuit *black = +120 volts (Bus A) *white = 0 volts (neutral wire) and *red = -120 volts In the world of 120V, bare = equipment ground (no current draws in from bare during operation) - that is why people recommend using 12/3 or 14/3 cables. The Romex cable is a Cables of this type come with a red jacketed wire, which should be used alongside the black cable for the two primary "hot" wires on a 240-volt circuit A circuit with a voltage of 12 volts. NM-D1913A was developed to help with NM-D1913A An insulation rating of 600V allows it to deal with voltages up to 240V. It is possible to feed a 240V circuit with 12/2 With the cable coming from a circuit breaker, I colored the white wire red with a red felt-tip permanent marker. This still would not pass an electrical inspection, but it addresses any electrical safety issues associated with running your heater with 12/2 cable, provided that the wires remain The National Electrical Code is not well enough known to me to say whether a black electrical tape on a white wire would pass an inspection - However, I'm not sure whether or not it would pass. Also, this is another indication that the white wire is not a neutral. *br> *br>The calculations of 8 show that the white wire is not a neutral. Using your 2000-watt system, 3 amps were drawn A 15A 240V breaker would be sufficient for this load a 20A breaker would not be dangerous. *Please do not use 12/2 for this load unless it is marked as 240V in a can't-trust-this-circuit installation. I'm sorry, but A person who works on your wiring may assume that the white wire has 0 volts on it when it has 240 volts when it works on the black wire - if you do not do it in the right fashion, this will cause problems. It may be forgotten by yourself one day and you could injure yourself or damage your property. A wrongly identified wire will leave you with a horrible wiring mistake. I wish you good luck with your

20 amps is the capacity of 12 gauge As a minimum, you will need a 10 gauge wire for a circuit that will provide 30 amps. The average person with no electrical training can find many excellent books on wiring for a low price to get all the information they need. Look around to see if the Black and Decker text is available For a camper, you will need to consider how it will handle rough weather conditions as well as the exterior methods and materials used.

See if your local code is correct. In our county, we are not allowed to pull romex through any conduit

It depends on the voltage. If it's 110 volts, it's fine, if it's 220 volts you'll need a I would think an 8000 but air conditioner would be 110 volt and not draw more than 20 amps as long as it didn't draw more than that.
