How do you connect a 240 volt electric heater It is a baseboard unit the has a black and red internal wire for connection Do you use 12 2 wire or 12 3 wire The thermostat has 2 red 2 black wire?
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 you wire two 12 volt car batteries to make 12 volt?
You would wire them in "Parallel". That means positive post to positive post and negative to negative. Two 12 volt batteries wired this way doubles the capacity and amperage capability of the system. It does not cause any harm to the electrical system as the system sees them as one big battery.
Will wiring 2 batteries in series hurt your boat?
Depends on the battery size. If your boat is a 12 volt system and you wire two 12 volt batteries in series you then have 24 volts. If the batteries are 6 volt batteries you will be fine. If you have a 12 volt system on your boat and want to use two batteries then wire two 12 volt batteries in parallel. You will still have 12 volts but will have double the amperage available and this will extend the running time of the batteries.
