There is nothing to keep you, if you are building your own equipment to put a circuit breaker in it for the maximum you want to see that equipment to pull. Then even if it is plugged into another circuit, the specific equipment is protected. Historically lots of people use fuses for this, but small circuit breakers are available from many suppliers.
Unless it is designed for it, please do not use circuit breakers as power switches. Normally power circuit breakers are not designed for the riggors of being turned on and off regularly. But are designed to go on or off and stay that way. Think of the way your house works, you don't use breakers to turn on and off lights in the house, but you often do turn the lights on or off multiple times a day. Using breakers to turn off power as a protective measure during maintenance is within their normal duties. But even at that, breakers to wear out eventually. I agree with Stevens warning, local laws/codes may no allow you to do your own wiring without inspections or being done by licensed professionals. Just check with your communities building inspectors to get a word of advice, at least that is what I would do. -- In my area, an individual is allowed to wire or re-wire one house per year for personal use without using a professional, but it must still be inspected and meet code. ><> ...
