Can I use 12 and 14 gauge wire with a 20 amp outlet no. 16352

He is correct. I'll not go into the particulars but the fact is, you have two separate circuits connected to the same breaker. Separate the two circuits by installing another 15-Amp breaker. Although I understand your situation, please understand wire gauge and electrical amperage are two different animals. Breakers are rated in Amperage and electrical conductors are sized by wire gauge. That said, the 20 gauge wire you speak of is actually a 12 gauge conductor and the 15 gauge wire as you say is a 14 gauge conductor. Have a good day.

Ideally you should run the line straight from the circuit breaker out to your hot tub, but if the line running from your circuit breaker to the box you're using now is 20amp. you can absolutely connected to that. to be up to code it cannot be an open box it needs to be closed After you wire in your 70ft connection. (that's assuming the box that you're using is dedicated already to your hot tub) then the only difference would be is your using extra line and costing you tenths of a penny extra and electricity per hour.

Hi Chris,

According to page 31 of the brochure, the switch accepts up to a #18 gauge wire ans is suitable for a 6 amp load at 125 volts or a 3 amp load at 250 volts. I recommend use of a solid conductor for this switch - but you could use a stranded wire type with similar results if you "tin" (solder) the wires first. I would not recommend the use of stranded wires with this switch. If you attempt to push a larger wire into the terminal opening, you could damage the spring metal contacts - rendering them inoperable.

The National Electrical Code limits the smallest sized wires installed in buildings to a #14 gauge wire. This is two sizes greater than the 18 gauge wire allowed by this switch. For this reason, the switch is designed to interconnect fixture wires only - not for use between the home wiring and the fixture wires.

If you need to connect a switch between the home wiring and the fixture, you should use a switch that has wire leads on it already, or install a short length of the smaller 18 gauge wire with an insulation rated for at least the voltage of the circuit (thermostat, doorbell, network, telephone wire is NOT acceptable) into the switch, and use a wirenut to connect the home wiring to the 18 gauge wires.

I hope this helps & good luck!

In most cases, you need a pair of Red/White RCA cables. Connect one set of ends (1 red + 1 white) to the external tuner's output and the other (white + red) to the input on the Amp.

Then you need double stranded wire to connect the speakers to the amp. one x double stranded wire for each speaker. You can use electrical cord from the hardware store (e.g. 18 gauge wire) or you can buy some speaker wire (16 to 20 gauge - use lower number wire (thicker) for higher power amp). 16 to 18 gauge wire for a 100 watt per channel amp if your speakers are less than 15 feet from the amp (wires are less than 15 feet long). If longer than 15 feet, use the 16 gauge wire. You can use 18 gauge for most anything else.

Any off-the-shelf GFCI sold today with work on 12-2 wire:
By code, 12-2 wire should be connected to 20 amp circuit breaker, but typically most switches and outlets wired to that circuit are rated 15 amp. Amp rating is printed on electrical devices.

While there is a practical limit for the number of outlets on a 15 or 20 amp general purpose lighting circuit in a _residence_, the National Electric Code (NEC) does not impose a # of outlets per circuit limit (residential ONLY).
However, some electrician's design general purpose lighting circuits in a residence using a point system. An outlet is 2 points and a light is 1 point. So, for a twenty amp circuit, (10 outlets x 2 points) = 20. Or, (5 outlets x 2 points) + (10 lights x 1 point) = 10 + 10 = 20. Or (8 outlets x 2 points) + (4 lights x 1 point) = 16 + 4 = 20. However you want to mix it up.

Now, if this is for a Commercial building, the the NEC allows no more than 180 VA (Volt Amps) per outlet. 180 VA / 120 Volts = 1.5 Amps.
20 amps / 1.5 Amps = 13.3 outlets. Drop the .3 and one determines that 13 outlets are allowed on a Commercial 20 amp circuit.

Also, if the 20 amp circuit is considered a continuous circuit (ON for more than 3 hours a day), then it can only be loaded to 80%. 80% of 20 amps = 16 amps.

A branch circuit protected by a 20 amp breaker requires 12 gauge wire. The freezer should by the only load connected on that circuit.

You only noted three prongs: ground, vertical and horizontal, so I am guessing (since I can not see it) that you have a 240V 20 Amp plug on your dryer. There should be a number on the face of the plug that tells what type it is (my guess: NEMA 6-20). As long as you have a minimum of #12 (20 Amp) 3-conductor cord feeding the existing outlet, you can purchase a new outlet, that matches your plug, and replace it. Verify the voltage and amperage required by reading the label that is on the back of the dryer or in the owners manual to be sure you get the right one. You will also need to verify the wiring and breaker at the main panel. Be sure that the wires go to a two-pole breaker that is rated for 20 Amps (or whatever the dryer is rated for) and not two individual breakers. If the dryer is rated 20 amps make sure you have a minimum of #12 gauge wire, if the dryer is rated 30 Amps, the wire needs to be #10 gauge.

The circuit is protected by the 15 amp breaker. That's what matters, the wire size and the breaker feeding it. It's OK to have a 20 amp recepticle fed by a 15 amp breaker.

In short - NO. 15 amp circuits are intended for lighting and outlets and usually have 14 gauge wiring. A 20 amp circuit is usually wired with heavier 12 gauge wire which can carry the increased amps. If you plug in a 20 amp breaker into a 15 amp circuit you run the risk of overheating the smaller gauge wire and starting a fire.
