First of all, are there any other appliances or lights on this circuit? If so, they must be included in the total wattage for the circuit. The fan units are either listed with the Amp rating or wattage rating (Volt Amp) VA. The total amperage allowed on a 15 A circuit is 12A.(80% of the total per NEC). The total wattage would be 1380 watts. ( 115 Volt single phase X 15A = 1725 watts, 1725 x 80% = 1380 watts)

### I have 110 volts n each leg but not 220 across both why??

In a traditional North American residential electrical panel (120/240 volt, single phase), installing a single width or single pole circuit breaker, you would expect to read 120 volts from the breaker terminal screw to either ground or neutral. A double width or double pole breaker would provide 120 volts from either of the breaker terminal screws to ground or neutral AND it will provide 240 volts BETWEEN the TWO breaker terminals.

A single-width circuit breaker case that contains two handles is NOT a two pole circuit breaker (these are called "tandem" or "1/2 size" breakers). This is because a single width breaker engages only one "line" in the panel. A double width breaker will engage 2 "lines" as a triple width breaker would engage 3 "lines" of a 3 phase panel. A single wide breaker can not physically engage more than 1 "line" so it will never be able to pass 240 volts.

You must install a double width / double pole breaker to safely supply a 240 volt circuit / device.

### 5000 watt inverter schematics circuit

If you have (90) 50w lamps = 4500 watts total. Assuming a 120/240 panel, if you put 1/2 on one "side" of the panel and the other 1/2 on the other "side" of the panel, that would be 2250 watts on each half. The generator should be rated *at least* 125% of the load; 4500w x 1.25 = 5625W. Using a 4500W generator on this load will cause it to overheat and shorten its life as it is running at 100% of capacity all the time..

One half of the panel is 120V to neutral, and the other is 120V to neutral - or 240V between both circuit breaker terminals. Ohms law for DC circuits and purely resistive AC circuits says Volts x Amps = Watts; or Watts / Volts = Amps. So, 2250W / 120V = 18.75A on each pole of a 2 pole circuit breaker that feeds the sub panel. A #12 copper wire is rated for 20 amps; but as per National Electrical Code - must be de-rated to 80% of rating which means it is good up to 16 amps maximum. A #10 copper wire is rated for 30 amps, but it too must be derated to 80%, making it good for 24 amps maximum. So, if you are going to feed a sub panel supplying (90) 50watt lamps, you will need to run a #10/3 copper cable from a two pole 30 amp circuit breaker at the generator to a 120/240 volt "main lug only" sub panel rated for at least 30 amps.

Divide your load evenly across the sub panel - (4) 15 amps circuits via (2) two pole 15 amp circuit breakers on each "side" of the panel if you run (2) 14/3 cables out to the lights - or (4) single pole 15 amp circuit breakers if you run (4) 14/2 cables out to the lights. No circuit breaker terminal should have more than 23 lamps that means you have (2) w/ 22 lamps and (2) with 23 lamps. The circuit w/ 23 lamps will draw 23 lamps x 50w = 1150W. 1150W / 120V = 9.6A. The 22 lamp load will be 22 x 50w = 1100W. 110W / 120V = 9.2A. Which is well within the 12A maximum allowed (after derating as required by code) by a #14 copper wire rated for 15A.

Good luck!

### We have a traditional black Hunter ceiling fan. The metal pull broke this morning. I can't turn off the fan or re-attach the pull cord

You can easily fix this. Turn the breaker off that runs the circuit the fan is on. It will likely be a 15 or 20 amp single pole breaker. If you don't know which one it is just turn off breakers until your fan goes off. Look closely at how the fan is assembled and remove the base that the pull mechanism is enclosed in. Them just remove what is left of the pull chain and replace it. They sell the pull chains at Home Depot or Lowes.
Hope this helps.

Turning off the circuit breaker to the circuit is sufficient, but if you feel better turning off the main, do it. Just turn the light ON then turn off one (single pole) circuit breaker at a time until the light goes out. Then, like you said, just match the wires.

Wiring is not fully described: Location of hot wire and neutral wire from breaker box are unknown.
If Hot wire arrives in ceiling box first, the switch box will not have white neutral wires that are twisted together and covered with wire nut. Neutrals will be in ceiling box.

What is known: You are replacing single pole switch attached to one 14-2 wire going to light.
You are replacing light with a fan-light and replacing switch with a 3-pole TM8111 switch.
You have replaced 14-2 wire with 12-3 wire.

Assume neutrals in ceiling box.
Assume Hot wire in ceiling box: Connect 12-3 black wire to black Hot wire. Connect 12-3 white wire to black wire on light. Connect 12-3 red to red wire on fan.
White neutral from fan and white neutral form light connect to other white neutral wires and covered with wire nut.
Wiring at switch:
Black Hot wire from ceiling box connects to A COM terminal.
White wire to ceiling light connects to A SP2
Red wire to fan connects to A SP1

Hi,
No you are getting a backfeed from somewhere else...either the neutral is no connected properly or you have a bad ground...

It has nothing to do with the amp. rating of the switch..

### I turned power off to wire a ceiling fan, when I reset the breakers the Dimmer witched do not work.

Did you remove the dimmer switch or alter the wiring whilst putting the ceiling fan control in the wall? If so you have obviously wired it back up the incorrect way. How many original wires were at the light/dimmer switch. Will need to know colours etc?

### Trying to install lsdc163pwv for ceiling light operated by 2 different switches. Install box is through switch with black common hot wire, red and black travelers and 2 white neutrals and grounds . New...

Found a .pdf file that shows LSDC163pwv ... it does not show wiring for LSDC. It shows wiring for other 3-way dimmers & separate wiring for 3-way fan control. This is a clue.

Let me provide what I know:
-Instructions might be confusing because LSDC works for both single-pole and 3-way circuits ... which probably adds a lot of extra wording in manual
-LSDC Device has single-pole/3-way dimmer (this requires 3 wires)
-Device has single-pole/3-way fan control with 3 speeds (which requires 3 wires)
-That's 6 total wires
-If I understand correctly, you just want to control a ceiling light? -And you do not have a fan? And your ceiling light is set up with 3-way switches.
-IF you are also wanting to control a fan in addition to the light, the box will need separate wires that go specifically to the fan >> your description shows that you do not have separate wires for the fan. Is this correct?
-Without separate wires to the fan, you can still control the light ... but if wires to light also turn the fan on-and-off, then the LSDC is not the right control since a dimmer for lights will not work on both fan and light.
To wire the light:
-You have identified black common wire for light (it is connected to dark-colored screw on 3-way switch)
-You have identified travelers that connect the 3-way switches
-The neutral wires seem to be twisted together at back of box.
-I think the dimmer is located on the top, and fan control is bottom?? Not 100% sure >>>
-Question: are there 3 wires that are associated with dimmer?
-If you can see 3 wires for dimmer, one of those wires should be black ... just hook that to common, and hook other 2 wires to travelers ... and see if it works. If not, keep connecting them until correct combination is found.

Tip- I read a lot of electrical part manuals, and when confused, I write out the instructions so it breaks down the information.

### I have the power source in the ceiling. I want to run wire to a single pole switch to a ceiling light?

Disconnect 1 side of light. Wire nut 1 wire from switch to 1 side of wire from light. Wire nut other side from switch to light. You now have a switch inline.

### How to do you wire 2 separate exhaust fans to a double single pole switch with a 20amp breaker problem

Your statement is a bit off the wall

Do you have two single pole switches or two double pole switches

You would normally provide a Live, Neutral and Earth to each fan via a switched , double pole, fused spur box .(You run a cable from the spur to a junction box) , you then run a LNE to each of the fans (using plastic trunking or conduit if the cables cannot be sunk into a wall).

Inside the junction box you remove the Live supply cable from the connector which should now be carrying three cables leaving the two cables running to the fans.

Put the Live wire into the spare connector inside the junction box

Get a twin and earth cable with the two wires marked up as Lives (Brown or Red in the UK, or whatever your wiring colour code dictates in your country) take those to a single pole switch which is convenient to you and wire them in

Back at the junction box put one of those wire into the connector where the two Supply wires for the fans are and tighten them up

Put the second wire from the On/Off switch to the Spare connector in the junction box which is holding the Live Supply

You then have a fused supply with a switch to break the circuit

If you do not need a switch then ignore the second part and just rely on using the switched fused spur to control them.

You can use a single pole switch but it is safer to stick with the double pole version

The breaker will be out of the loop as that will provide the power and you should not be fitting wires to it
