It is perfectly acceptable to have (2) 120 volt 15 amp receptacles operated from a 120 volt 20 amp circuit breaker (as a general rule of thumb 11 receptacles are acceptable on a 20 amp circuit). The 15 amp rating of the receptacle is the maximum allowed amperage that should be hooked up to the receptacle at any one time. So in this case the limiting factor is the amount of current being drawn across both receptacles simultaneously should not exceed the 20 amp rating of the circuit breaker.
In the United States the NEC code allows the use of a 20 amp circuit breaker to feed a branch circuit consisting of 15 amp receptacles. Generally you would not exceed 11 receptacles though as you will assume an average load of 1.5 amps per receptacle and trying to maintain about 80% max load.
A 225 amp load will physically not be able to tie into a 15 amp breaker and a duplex receptacle as you can not get a 3/0 wire under the breaker and receptacle terminal screws.
Yes. An everyday occurrence of this circuitry is in your kitchen counter split receptacles. The top half of the receptacle is a 15 amp circuit and from the same breaker the bottom half of the receptacle is another 15 amp circuit. A two pole single handle breaker is a common trip. If one of the circuits fed from the breaker faults the other connected circuit will shut off also. If you are talking about slot position in a breaker panel, you can remove the two pole breaker and install two single pole breakers.
No there are no adapters made for these types of installations. The reason there are no adapters is to provide a factor of safety. To plug a 30 amp plug into a 50 amp receptacle could allow 50 amps to be applied to a 30 amp rated cord. The 50 amp receptacle is more than likely being fed by a 40 amp breaker. Just change the plug cord to match the ampacity of the breaker ahead of the 50 amp receptacle. Or change the 50 amp receptacle and 40 amp breaker to a 30 amp breaker and use your existing cord plug.
No. Also it would be a moot point using a 20 amp receptacle because the breaker protecting the circuit will only be a 15 amp. If you use a 20 amp breaker then make sure that the wire size is #12 and that you remove the 15 amp receptacle from the circuit as it will be not rated for the new 20 amp current.
A 15 amp circuit breaker is used to protect a # 14 copper wire which is the minimum size wire that can be connected to a 15 amp receptacle.
A 225 amp load will physically not be able to tie into a 15 amp breaker and a duplex receptacle as you can not get a 3/0 wire under the breaker and receptacle terminal screws.
Yes as long as you change the 50 amp breaker to a 15 amp breaker. You will be hard pressed to get the 50 amp #6 wire under the terminals of the 15 amp receptacle.
In North America you would need two 15 amp breakers to obtain 240 volts. The wire for a 15 amp circuit would be #14 AWG. So to answer the question, yes a 240 volt receptacle can go on a 15 amp circuit.
The 240 volt receptacle has to have an amperage rating. It is this rating that governs the wire size and breaker size to feed the circuit. The new two pole breaker will be inserted in the 100 amp distribution if space is available and connected to the new wiring that terminates at the new receptacle.

A 15 amp circuit breaker is used to protect a # 14 copper wire which is the minimum size wire that can be connected to a 15 amp receptacle.
No. The breaker must protect the circuit components such as wiring, outlets and switches that are connected to the breaker. Therefore if you have a 30 amp circuit as dictated by its components you need to protect it with a 30 amp or less breaker.
Replace the 30 Amp Breaker with a 15 Amp breaker.
Yes you can use #14 AWG romex for a receptacle as long as the breaker protecting it rated 15 amps or less. If it is a 20 amp rated circuit then you will need to use #12 AWG.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
