What size wire for 50 amp breaker
For a 50-amp hot tub that can accommodate about 6 to 12 people, it is advisable to use 6-gauge wiring. However, some manufacturers state that you can use an 8-gauge wire instead, but it is better to use a 6-gauge wire to stay on the safe side. Few hot tub owners worry about which wire size to use for the ground and breaker wires.On top of that, we will also calculate the 150 amp wire size for service 50 feet, 100 feet, 150 feet, 200 feet, and up to 500 feet away from the source. ... I my examples above I asked about 150 and 200 amp breaker boxes. Would the amperage per wire be roughly 1/2 because there are going to be 2 wires carrying it? Thanks Chuck. Reply.For 50 amps, you could use 4 AWG wire with 85A ampacity (a bit of overkill but it’s OK), but you can never use 8 AWG wire with 50A ampacity (you will fry the circuit). In most cases, 6 AWG is an almost perfectly-sized wire for a 50 amp breaker.
