How much electricity does a 3 HP motor use?
3 hp is 2.2 KW. Considering 400 Volts at the terminal for 415V Motor and 85% Efficiency, it will draw 2200*0.85 i.e. Input KW =2.58 KW. Hence, the Power Consumption will be 2.58 KW at Full Load.
How many amperes current is in 220V supply?
V is 220V AC in most countries. So for example if R = 220 , the current will be 1 amp.
Can I use 12 gauge wire on a 30 amp breaker?
No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps. … Electrical current is measured in amperage (amps), and each wire gauge has a maximum safe carrying capacity.
What size breaker do I need for a 5 hp motor?
In fact code recommends a 60 amp circuit breaker for a 5 hp 230v motor, but with overload protection.
How many amps is 3 horsepower?
