How do you calculate amps in a 3 phase circuit?
Divide the power consumption in watts by the line voltage multiplied by the power factor to find the amperage. For three phase circuits the power factor is the square root of 3. If your calculator doesn’t have a square root function, use 1.73 as an approximation of the square root of 3.
How many amps is 115 volts 60 Hz?
How many amps does a single phase 115 volt 1 HP 60Hz pump draw? Whatever the voltage, 1HP equates to 760W. Watts = Volts x Amps. Your voltage is 115 so the current is given by 760/115, roughly 7A.
What size breaker do you need for 115 volts?
A 115 or 120-volt individual, properly-grounded branch circuit with a 3-prong grounding type receptacle, protected by a 15 or 20 amp circuit breaker or time-delay fuse.
What gauge wire is required for a 40 amp circuit?
8
What gauge wire is needed for a 20 amp circuit?
12-gauge
Can I use 14 gauge wire for lights on a 20 amp circuit?
You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals.
Is it okay to use a heavier gauge wire?
Using larger gauge AWG wire offers you more flexibility in how your electrical system is laid out. Your electrician can add more outlets when your wiring has increased current potential. Larger wiring can sometimes be installed in risky areas where small wiring is not recommended.
How long should a 27 mil pool liner last?
Vinyl liners last 5-9 years, with a general rule being the thicker the liner, the closer it will be to 9 years. But beyond that, a thicker vinyl liner is a good investment in avoiding potential problems. They can withstand more damage without leaking and will require fewer patches and repairs.
How long will a 20 mil pool liner last?
about 10- 12 years
What is thicker 20 or 27 mil?
The correct term for liners is mil, although this is not short for millimeter. It is the term that represents 1/1000th of an inch. Therefore, 20 mil = 0.020 inch and 27 mil = 0.027 inc.
