What size breaker do I need for a 15 amp motor?
Re: Correct breaker size for 15A compressor.
If you notice it says “thermally protected motor”, which means the motor has built in overload protection.
The 20A breaker is protecting the feeder wires, not the motor.
If you ran 12 AWG wire, then you can use a 20A breaker, 14 AWG requires a 15A breaker..
What is the standard fuse size?
The standard ampere ratings for fuses (and circuit breakers) in USA/Canada are considered 15, 20, 25, 30, 35, 40, 45, 50, 60, 70, 80, 90, 100, 110, 125, 150, 175, 200, 225, 250, 300, 350, 400, 450, 500, 600, 700, 800, 1000, 1200, 1600, 2000, 2500, 3000, 4000, 5000, and 6000 amperes.
Can outlets and lights be on the same circuit?
Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes. Check with local authorities on those limitations but yes it can be done. … Also be sure to install a GFCI receptacle, not a conventional duplex receptacle.
Will a 15 Amp saw trip a 15 amp breaker?
If it’s truly pulling 15 amps then yes. A 15A breaker will hold 80% of its current rating, which means at 12A, it will trip. That’s not how any breaker or fuse works. … If the device is rated at 15A, and it’s the only device running on the circuit, it should not be tripping a 15A breaker.
How many amps does a 10hp motor pull?

How many amps will a 20 amp breaker hold?
16 ampsThe standard for most household circuits are rated either 15 amps or 20 amps. An important note to remember is that circuit breakers can only handle about 80% of their overall amperage. That means a 15-amp circuit breaker can handle around 12-amps and a 20-amp circuit breaker can handle about 16 amps.
What size breaker do I need for a 5 hp motor?
60 ampIn fact code recommends a 60 amp circuit breaker for a 5 hp 230v motor, but with overload protection.
How do I know what size fuse I need?
The fuse rating can be calculated by dividing the power used by the appliance by the voltage going into the appliance. I (Amps) = P (Watts) ÷ V (Voltage).
How do I know what size fuse to use?
B Calculate MINIMUM FUSE AMPERAGE by multiplying product amperage rating by 125%. Minimum fuse amperage provides more protection for the wire but may result in nuisance blows. Example: 80A x 125% = 100A. C Choose FUSE AMPERAGE near the middle of this range.

What size breaker do I need for a 3 HP motor?
A 20 amp breaker is all you’d ever need for a 220v 3HP motor.
What happens when you put a 20 amp receptacle on a 15 amp circuit?
If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for. If you exceed 15 amps, the breaker will blow, and protect the receptacle. The inverse is not true.
How do you size a 12v fuse?
Find the size of fuse by multiplying the amps required by the device (2) by 1.5. 2×1.25 = 2.5 then we will round up to the nearest fuse size (in multiples of 5 amps) which would call for a 5 amp fuse.
How do you size a circuit breaker for a motor?
You must size the conductors at 125% of the motor FLC [430.22(A)]. You must size the overloads no more than 115% to 125% of the motor nameplate current rating, depending on the conditions [430.32(A)(1)]. You must size the short-circuit ground-fault protection device from 150% to 300% of the motor FLC [Table 430.52].
What size breaker do I need for a 7.5 hp motor?
Re: Wire and breaker size for 7.5 hp motor You need 50 amp rated wire with a 50-100 amp breaker.

How many outlets can be on a 20 amp circuit?
10 receptaclesOne rule of thumb is to assign a maximum draw of 1.5 amps to each receptacle, which allows for 10 receptacles on a 20-amp circuit.
