Whatever you put on the input, install an AFDD with spark protection. Input devices work in almost the same way, and only this thing protects against fire.
The choice of a circuit breaker depends on the cross-section of the input / output cable, as well as the rated current and total power that may occur when using electrical appliances in a private house.
If you take an introductory machine from a good manufacturer, then it will be quite reliable. In any case, it will work in a timely manner in the event of a short circuit and thermal overload exceeding the rating.
Do not install a machine designed for heavy load on a network with an inappropriate small cable section.
