# How Many Watts Will A 20 Amp Breaker Handle?

## How many LEDs can be on a 20 amp circuit?

38 lights20 amps / .

4545 amps per light = 38 lights..

## What size breaker do I need for a 1500-watt heater?

15.6 ampsA 1500-watt heater on a 120-volt circuit thus needs a breaker of 15.6 amps. Because a 15-amp breaker would be too small, you need a breaker with the next highest rating, which is 20 amps. Include the current draw of any other devices on the circuit when calculating the breaker size.

## What gauge wire do you use with a 20-amp breaker?

Amperage and Wire Gauge Building codes based on the National Electrical Code prohibit the use of 14-gauge wire anywhere on a 20-amp circuit. All wiring in such circuits must be 12-gauge or larger.

## What can a 20 amp circuit support?

A 20-amp breakers can support up to 2,400 watt on a single circuit. The safe maximum for a 20-amp circuit is 1,920 watt, but circuits should not be loaded to more than 80 percent of their maximum capacity.

## How many amps is 600 watts?

## Can I put lights and outlets on the same circuit?

My short answer to the question is that “Yes, lights and power outlets (a.k.a AC receptacles) can be on the same circuit controlled by a circuit breaker, especially in a single family residential house”. … The circuit branch controlled by the 15A circuit breaker has a couple of lights and AC outlets connected.

## 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.

## Can I use 14 gauge wire 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. … Just use the side terminals.

## Can you run lights on a 20 amp circuit?

The National Electrical Code, NEC has no such limitations. Lighting fixtures can be put on any 20 amp circuit except those that are required by code not to have lighting fixtures (washer, kitchen small applicance, and dedicated equipment circuits).

## Can you use 12-gauge wire on a 20-amp circuit?

As a general rule, 12-gauge wire can safely employ 10 receptacles on a 20-amp circuit using copper wire. By comparison, 14-gauge wire can handle 15 amps and 8 receptacles.

## How many watts is a 15 amp breaker?

On average, a 15 amp breaker can run a one 1K light each without blowing or about 1800 – 2000 watts. The only issue with relying on this formula is that it is advisable to only load a breaker up to 80 percent of its capacity. Overloading a 15 amp breaker can lead to very dangerous situations.

## How many watts can a 20 amp double-pole breaker handle?

3,840 wattA circuit running on a 20-amp double-pole breaker can have any combination of heaters up to 3,840 watt. You can install two 1,500 watt heaters if you use just one thermostat.

## Do I need 20 amp outlets in kitchen?

Kitchens, by code, are required to have at least two 20 amp, 120-volt circuits to be installed on every kitchen countertop. The main reason for this is so the outlet can handle enough amps to power simple kitchen cookware such as microwave ovens, toasters, and blenders.

## How far can you run a 20 amp circuit?

For a temperature of 100 °F and a current of 20 A (ampacity of circuit), a length of 53 feet will cause a voltage drop of 3.6 V. So to be conservative I would say 50 feet is the max length on a 120 V, 20 A permanent branch circuit. The NEC might say otherwise, though.

## How many outlets can I put 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 many LED lights can be on a 15 amp circuit?

180Each CFL or LED bulb typically gives the same amount of light as a 60-watt incandescent bulb while drawing 10 watts or less, which is equivalent to a current draw of 1/12 amp. Thus a 15-amp circuit can safely control 180 or more fixtures that use CFL or LED bulbs.

## How many devices can be on a 20 amp circuit?

ten devicesBecause not all the outlets will be used (drawing power). However, they do put a limit on the maximum power load a circuit and its breaker should carry – no more than 80% of its rating. This means a 20 amp circuit should only carry 16 amps at maximum – or about ten devices.

## Will 12-gauge wire carry 20 amps?

12-gauge wire is the next size larger and is allowed to carry up to 20 amps. As a result, the amp rating of a circuit breaker has the following relation to the wire size that has been chosen. A 20-amp breaker is never* allowed to run any circuit whose wires (anywhere on the circuit) are 14-gauge.

## How many outlets and lights can I put on a 20 amp breaker?

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.

## How far can you run 12 gauge wire on a 20 amp circuit?

The total circuit would be about 60 -70 feet in length. It would only be supplying about 5 outlets and one light. It would be a light load, running small things, no heaters or med/large equipment. #12 provides reasonable performance up to about 100′ with general loads like you describe.
