## 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 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 amps is a 1 HP well pump?

10 ampsA 240 volt, 1 horsepower well pump draws 10 amps of current.

## 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. It wouldn’t hurt anything to run 30amp circuits if you so choose, but it’s overkill.

## How many amps does a submersible pump need?

A 1 HP submersible pump engine will draw a 3.2-amper current if it is a single-phase motor at 230 volts of voltage. If it is a three-phase motor at 440 volts, it will draw a maximum 1.7-amper current.

## How many outlets can be on a 15 amp circuit?

10 outletsGenerally, homes have eight to 10 outlets on a 15 amp breaker but not all are used at the same time. Lights and outlets are normally wired on separate branch circuits, which means that the lights will be protected by a separate circuit breaker to the one which protects the outlets.

## How do I know what size motor breaker I need?

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].

## 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. Cross Reference that fuse size to verify that it’s below the Maximum fuse size called out by this chart.

## What are the standard breaker sizes?

Standard sizes for fuses and fixed trip circuit breakers, per 240.6, are 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 amps.

## What size breaker do I need for a 230v well pump?

20 ampAccording to code, the largest breaker size allowed for a 1 HP motor operating at 230 volts is 20 amp.

## What size breaker do I need for a 1/2 HP well pump?

15 amp 2Reach4 Well-Known Member The manual for your pump probably recommends a breaker size. For a 1/2 HP submersible pump, a 15 amp 2 pole breaker would be normal. You can run 12 AWG, but unless the run is very long, 14 AWG is sufficient. Bigger wire would let you switch to a bigger pump later if you wanted.

## How many amps does a 1.5 HP pool pump draw?

17 AmpsThe 1.5HP pump is drawing 17 Amps on initial start up for about 2 seconds (literally), and then drops to 12 Amps and hums away.

## How do I size a motor overload?

The overloads are determined using 125% of the FLA, 7A x 1.25 = 8.75A. The maximum allowable size for the overloads is 9.8A. The overloads can be sized at 140% of the FLA if the overloads trip at rated load or will not allow the motor to start, 7A x 1.4 = 9.8A.
