How many amp breaker should be used on a new 220 hot tub install,and is it easy enough to install in my breaker box. Also what type of wire is used to reach the hot tub approx 25 feet away from breaker box::;)

Typically most hot tubs need a 50 amp circuit with #6 Romex cable. But you should find the nameplate to confirm the wattage/amperage and size the circuit accordingly.
