It depends what is the make and model of the planer you just bought? Most 5HP motors require a 30A service but if the running load is only 15A then a 20A breaker can be used. You cannot use the 50A breaker for this or the wire run for it, you run a massive risk of starting a fire or killing the machine if it did have a sudden surge for whatever reason.

If it only needs a 220V 20A breaker you can get a double pole breaker to fill that slot where the 50A was and run some new 12/2 AWG line (usually it’s yellow now in the big box stores) with a similar outlet and you’re in business. If it requires 30A can the breaker to the correct amperage and adjust the wire to 10/2 AWG (usually its orange now in the big box stores) with a similar outlet.

If you don’t know what you’re doing please call an electrician as that many amps can do some serious damage and kill you very easily.
