How many watts can you run on a 14 gauge wire?
#14 gauge cable has a rated capacity of 15 amps or 1800 watts (at 120 volts). 1800 watts divided by 575 watts per light = 3.13 instruments. Obviously you can not have a .13 lamp. 8.
Copper cabling typically consists of 4 pairs of wire (8 total conductors) wrapped in a single jacket. For example, 14/2 indicates that there are two 14-gauge wires (a ground wire, if part of the cable, is not included in this number) within the cable.
- 14–3 cable (14 AWG–3 insulated conductors) allows you to have two separate hot conductors sharing the same neutral. Short answer, you use a 14-3 cable to wire a home light that is controlled by two different switches. Slightly longer answer. The 14 refers to the gauge, or thickness of the wire.
- A rating of 14/3 refers to the gauge of the wire and how many conductors are in the cable. In this case, the wire gauge is fourteen (lower numbers mean larger wires) and the three indicates that there are three conductor wires in addition to a non-insulated ground wire.

I spoke with an electrician in the area that told me on older systems, it was fine (but not for new construction). Apparently, a 14 gauge wire can carry 20 amps safely but the "powers-that-be" say it can only carry 15 amps just as a built-in safety measure.

I'm ask so many times how many outlets and or lights can I put on a 15 amp or 20 amp breaker. Well NEC code does not have it listed that way. By rule of thumb you would stick with 8 to 10 outlets and or lights per breaker. Now this is of course they are 120 volts 60mhz (USA or Canada).
- A receptacle outlet must be installed in every kitchen, family room, dining room, living room, sunroom, parlor, library, den, bedroom, recreation room, and similar room or area so that no point along the wall space is more than 6 feet, measured horizontally along the floor line, from a receptacle outlet [210.52(A)] (
- As the other two posters have indicated, it depends. For 20 AMP you have 20A*120V or 2400 watts and 15 AMP you have 15A*120V or 1800 watts. Good Electricians will only plan for 80% load so you have 1920 and 1440 watts respectively at your disposal per circuit.
- A 1000w HPS or Metal Halide light takes 9 amps at 120 volts so you can only run one on a wall outlet circuit. A standard dryer outlet is 220 volts and 30 amps so you can power up to six 1000 watt lights on that circuit.
