## What cable do you use for 12v lights?

Wire Gauges and Sizing

Most household lighting fixture, as well as many appliances, requires about 12- or 14-gauge wire. This is usually indicated as a number and a dash and then another number. For example, 12-2 or 12/2.

## How many amps can 14-gauge automotive wire handle?

The 14-gauge wiring works for 50 amps at 5 feet, 40 amps at 7 feet, 30 amps at 10 feet, 15 to 18 amps at 15 to 20 feet and 11 to 12 amps at 25 feet.

## 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 watts can you run on 16 gauge wire?

## What cable do I need for outdoor lighting?

Once outdoors, you should supply your lights via 1.5mm² three core steel-wire-armoured cable (SWA). Make sure that you only fit weatherproof lights that are suitable for outdoor use and that your circuit is RCD-protected.

## What wire do I use for lights?

Lighting circuits are generally run in 1mm2 two-core-and-earth cable, but particularly long circuits can use 1.5mm2 cable to compensate for the drop in voltage experienced on long cable runs.

## Can I mix 12 gauge and 14 gauge wire?

Yes you can mix 12 and 14 gauge wire with a 15 amp breaker on the circuit. But it is not recommended because the next homeowner or electrician may be confused and put a 20 amp breaker on it again.

## What is 16 gauge wire used for?

16-gauge are used for light-duty extension cords supporting 13 amps. 14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps.

## What happens if wire gauge is too big?

What happens if wire gauge is too big? A larger guage wire will carry more current for any given distance than a smaller guage wire will. You should ALWAYS size the wire to the load it will carry.

## How many outlets can you put on a 14 2 wire?

You can use 14-2 wire to 12 outlets that are protected by a 15 Amp breaker. If you use 12-2 you can use a t-rated 20 Amp receptacle, but in my code you only see those in kitchens.

## Can I use 14 gauge wire on a 20 amp breaker?

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 OK to use 12 gauge wire on a 15 amp circuit?

Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.
