Wow! This is interesting!
Even though non-grounding, non-polarized outlets may still be for sale in some hardware stores, nowadays every newly-installed outlet should have a ground.
A lot of homeowners may want to save money but, if the wires are larger than 18 gauge, leave them alone and call a professional to save families and homes from electrocutions and fires.
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

I would have to say that the amperage label on the main breaker would designate the amount of amps coming into the house.>Look at the number on the handle of the main breaker. That number is the rating of the breaker and at what amperage the breaker will trip. If you have a main fuse switch the number on the fuse is the tripping amperage. This will be the amount of current that the service is rated at.
No. The ampacity of a #12 wire is 20 amps. Being connected to a 30 amp breaker means that the wire can be overloaded by 10 amps and still not trip. There are two things that can be done to stay within the electrical code. Number one, change the two pole 30 amp breaker to a two pole 20 amp breaker. The load of the heater is I = W/E, 2000/240 = 8.3 amps. That load can be run on a 14-2 cable from a two pole 15 amp breaker. Remember that the breaker protects the size of the wire that is connected to it. Number two, if you want to use the 30 amp breaker then a #10 wire rated at 30 amps is the smallest wire to connect to that breaker.
Simple. Your main electrical panel will have a "main breaker". This will be a two pole breaker, usually at the top of the panel. It will have a number on the breaker "handle" such as 150 or 200. This is the maximum number of amps your panel can supply. Most newer homes, 1975 and newer have a 200 amp service.
A circuit breaker has a specific amperage trip setting. That is the number on the handle of the breaker. When an amperage that is drawn by a load goes higher than the setting on the breaker, the breaker will trip off. This tripping action opens the circuit and drops off the load that was causing a higher than normal amperage.
One and half breaker system is an improvement on the double breaker system to effect saving in the number of circuit breakers. For every 2 circuits, 1 spare breaker is provided: Two feeders are fed from two buses via their associated circuit breakers and these two feeders are coupled by a third circuit breaker which is called tie breaker. During failure of any of the two feeder breakers, the power is fed via the breaker of the second feeder and main breaker (tie breaker).
There are several factors: the outlet configuration and connection, the supply wiring, and the breaker. It has been suggested that: :The 240v gauge wire may be thicker than the 120 volt gauge. The 120 is 12 gauge and the 240 is probably at least 10 gauge. The wire itself will probably be okay. The outlet will have to be changed to a regular receptacle. The breaker for that circuit will have to changed to a 20 amp instead of the 30amp or so that it is now. I hope this helps you some. However, this ignores the fact that you can deliver twice as much power at 240v than 120v using the same rating wire and breakers. P= v x i; double the voltage, double the power for the same number of rated amperes. In any event, the cable into the breaker box will have to be disconnected from the two-pole breaker and the black (hot) wire connected to a single-pole breaker (say, 20A), and the neutral (white) wire connected to the neutral bar. There should also be a bare or green grounding wire connected to the grounding (or neutral) bar. The supply wiring must be at least 12 AWG or larger diameter (i.e., a lower number is larger diameter). In an ordinary north American receptacle, the black "hot" wire goes to the narrow slot, the white "neutral" goes to the larger slot, and the bare "grounding" wire goes to the third prong, often via the green screw marked "ground". Local code may dictate exactly how grounding connections are made (i.e., directly from the cable or with green pigtail from metal outlet box connected to the supply ground and the device ground). If possible, install a GFCI for added safety. Needless to say, any necessary rewiring of breakers and outlets should be done carefully by a qualified electrician, and you may need a permit, if not an inspection. It is also possible that someone illegally connected more than one outlet to the same circuit, so you should make sure there are none before any conversion project is undertaken, and account for any "extra" wires in the outlet box.
