## How many amps can a normal extension cord handle?

14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and **15 amps**. 12-Gauge Cords: If your tool load is between 10 and **15 amps** and the length of the cord is 50 to 100 feet, you need a 12-gauge cord to safely power any tool. This is a great extension cord for many purposes.

## How many watts can 12 gauge wire handle?

General Purpose Cords

14 – Wire |
12 – Wire |
---|---|

Recommended 80% Wattage Load: 1440 watts (120 volts). Max Wattage Load: 1800 watts (120 volts). |
Recommended 80% Wattage Load: 1920 watts (120 volts), 3840 watts (240 volts). Max Wattage Load: 2400 watts (120 volts), 4800 watts (240 volts). |

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

Originally Answered: How **far can you run 12 gauge wire on a 20 amp circuit**? **You** don’t want the voltage drop to exceed 3%, or 3.6 V. A length of 53 feet will cause a voltage drop of 3.6 V. So **I would** say 50 feet is the max length on a 120 V, **20** A permanent branch **circuit**.

## How many amps is a 10 gauge extension cord?

**12** Gauge for 8-10 Amps. 10 Gauge for 11-15 Amps.

## How far can you run a 30 amp extension cord?

The actual answer is: “there is no maximum, as **long** as it is rated for **30 amps**“. The question **should** be not how many feet, but how many **cords**. A 100 ft **extension cord** rated for **30 amps** is not the same, at all, as two 50 foot **30 amp extension cords**.

## Is 12 AWG speaker wire overkill?

The lower the **gauge** number, the thicker the **wire**. Thick **wire** (**12** or 14 **gauge**) is recommended for long **wire** runs, high power applications, and low-impedance **speakers** (4 or 6 ohms). For relatively short runs (less than 50 feet) to 8 ohm **speakers**, 16 **gauge wire** will usually do just fine.

## Should I use 12 or 14-gauge wire?

If you’re **wiring** a circuit on which there are both lights and outlets, or you just aren’t sure which **wire gauge** to **use**, you can’t go wrong by choosing a **12**–**gauge wire**. It’s not quite as flexible as a **14**–**gauge wire**, and it costs a bit more, but it’s always a safe choice on a 15- or 20-amp circuit.

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

Technically, you can have as many outlets on a 15 amp circuit breaker as you want. However, a good rule of thumb is 1 outlet per 1.5 amps, up to 80% of the capacity of the circuit breaker. Therefore, we would suggest a maximum of **8 outlets** for a 15 amp circuit.

## What is a 12 3 wire for?

The red on a **12**–**3** is used for three-way light switches which are covered later. **12** gauge Romex is rated for 20 Amps and is commonly yellow jacketed.

## 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 can I run on a 20-amp breaker?

One 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**.

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

Electrical plugs designated as **20**–**amp** will not fit into 15-**amp** outlets. A 15-**amp circuit** is usually served by 14-**gauge wire** and is protected by a 15-**amp circuit breaker** or fuse. A **20**–**amp circuit**, protected by a **20**–**amp breaker** or fuse, must be served by **12**–**gauge** or 10-**gauge wire**.

## What is the best heavy-duty extension cord?

**Here are the best extension cords:**

**Best**overall: Coleman 14 Gauge 100 Ft.**Extension Cord**.**Best**with a**power**strip: Anker**Power**Strip**Extension Cord**.**Best heavy**–**duty extension cord**: Watt’s Wire 14-Gauge**Extension Cord**.**Best**indoor**extension cord**: Iron Forge Cable**Extension Cord**.

## What is the heaviest duty extension cord?

**Heavy-Duty Extension Cords**

- Uses: tools and heating appliances drawing up to 15 amps of power.
- Cord length up to
**25 feet**: use 14 AWG wire. - Cord length up to
**50 feet**: use 12 AWG wire. - Cord length up to 100 feet: use 10 AWG wire.

## What gauge extension cord do I need for a leaf blower?

**Leaf blower**.

For **blowers will** 12 amps or less, use a 16-**gauge** light-duty **cord** within 50 feet of your outlet. Go with a 14-**gauge** medium-duty **cord** for a higher amp or a greater distance from the outlet.
