3 Phase Breaker

What size of Circuit breaker 5 Hp motor 40 amp.

1 hp = 746 Watts (1 horsepower = 745.699872 watts) so 5 hp = 3,730 watts

So if: “I” stands for current (flow of electricity) “A” stands for ampere (unit of current)

“V or E” stands for Voltage (current flow)“P” stands for Watts“R” stands for resistance (ohms)

I

What size of Circuit breaker R = E/I R = 220/ 40 R= 5.5E= I x R 40 x 5.5 E = 220 P = E x I 220 x 40 P = 8,800 all we needed was P = 3,740Wire size = # 8

1 hp = 746 Watts (1 horsepower = 745.699872 watts) so 5 hp = 3,730 watts
