Transcript of Electrical Stuff From Questions Friday. Delta 3 Phase Motor.
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)
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
