Since it is a 30 amp heater you need to run #10 gauge wire and use a 2 pole 30 amp breaker, since it is 208/240 volts. I hope this helped you.

Wiring a dimmer switch with 208vac, single pole


208 Volt 2-wire is generally achieved by pulling two hot wires off 3-phase 120/208 Wye or 208 Delta, or Highleg to center tap off high leg delta.
http://waterheatertimer.org/How-to-wire-3-phase-electric.html
http://waterheatertimer.org/images/3-phase-timer-diagram3-T104-208-240.jpg

Since each of these three phase systems also offers 120volt for lights, and a dimmer can be used for lights, then I wonder what you are using dimmer for?

208 volts.can be controlled by turning off one hot of the two hot wires.
Install dimmer on one of the hot wires, and see what happens.
Is the dimmer rated for 208 volts?

Add a comment and say what you discover.

I need to wire up a baldor 3 phase motor 208-230/480 15hp and dont have the wiring diagram to know what wire is what or where to hook it to?


Hi Casey, I'm an electrician and can help you with this problem.

First, a disclaimer. Without the catalog number of the motor you have, or a wiring diagram for it, no one can tell you how to wire this motor with any certainty. With that said...

Nearly all single speed 3 phase motors have 9 leads (numbered 1 thru 9) and can be wired for either "high" or "low" voltage. Most of the time, high is 480 volts and low is 208/240 volts. Given that you posted the amperage as "41-38 / 19", I am 99% confident that 41 amps is at 208 volts, 38 amps is at 240 volts and 19 amps is 480 volts. Further below is the way to wire unless the motor manufacturer or name plate indicates differently. You will need to determine the voltage of the appliance this is going to be installed into. You should be able to find this on a name plate of the appliance - but it may provide a dual voltage spec here, too. If this is the case, you will need to *carefully* measure the voltage with a meter, or find out the voltage of the electric panel that feeds the appliance.

Once you have learned the incoming voltage, you will connect the motor as such when L1, L2 and L3 are the line voltage supply wires and wires 1 thru 9 match the numbers on the nine wires from the motor.

208/240 or "Low" volts:
Motor leads 4, 5 & 6 connected together and wirenut.
Motor leads 1 & 7 to L1 and wirenut.;
Motor leads 2 & 8 to L2 and and wirenut and lastly,
Motor leads 3 & 9 to L3 and wirenut.

480 or "High" volts:
Motor lead 1 to L1 and wirenut,
Motor lead 2 to L2 and wirenut,
Motor lead 3 to L3 and wirenut,
Motor leads 4 to 7 and wirenut,
Motor leads 5 to 8 and wirenut and lastly,
Motor leads 6 to 9 and wirenut.

The motor should be operated briefly or "jogged" to determine the direction the motor turns. If the motor rotation needs to be changed, simply swap any two "L" wires (swap L1 and L2, or L1 and L3, or L2 and L3). Test once more to verify rotation and when correct close the wiring compartment and complete the installation. Swapping the L wires will likely be much quicker and easier to do at the magnetic contactor instead of the the motor's wiring compartment. Either location is acceptable.

You should try to obtain the name plate data for this motor - if at all possible to to make sure of the voltage and wiring method. I hope this helps & good luck!

Trying to change plug from a 3pronge hookup to a 4.The dryer only has 3 wires to hook up extenstion plug has white,red,black,green ...what do i do


It is your responsibility
 To contact a qualified electrical installer.
 To be sure that the electrical connection is adequate and in
conformance with the National Electrical Code, ANSI/NFPA
70-latest edition and all local codes and ordinances.
The National Electric Code requires a 4-wire supply
connection for homes built after 1996, dryer circuits involved
in remodeling after 1996, and all mobile home installations.
A copy of the above code standards can be obtained from:
National Fire Protection Association, One Batterymarch Park,
Quincy, MA 02269.
 To supply the required 3 or 4 wire, single phase, 120/240 volt,
60 Hz., AC only electrical supply (or 3 or 4 wire, 120/208 volt
electrical supply, if specified on the serial/rating plate) on a
separate 30-amp circuit, fused on both sides of the line. A
time-delay fuse or circuit breaker is recommended. Connect
to an individual branch circuit. Do not have a fuse in the
neutral or grounding circuit.
 Do not use an extension cord.
 If codes permit and a separate ground wire is used, it is
recommended that a qualified electrician determine that the
ground path is adequate.
Electrical Connection
To properly install your dryer, you must determine the type of
electrical connection you will be using and follow the instructions
provided for it here.
 If local codes do not permit the connection of a neutral ground
wire to the neutral wire, see "Optional 3-wire connection"
section.
 This dryer is manufactured ready to install with a 3-wire
electrical supply connection. The neutral ground wire is
permanently connected to the neutral conductor (white wire)
within the dryer. If the dryer is installed with a 4-wire electrical
supply connection, the neutral ground wire must be removed
from the external ground conductor screw (green screw), and
secured under the neutral terminal (center or white wire) of the
terminal block. When the neutral ground wire is secured under
the neutral terminal (center or white wire) of the terminal block,
the dryer cabinet is isolated from the neutral conductor.
 A 4-wire power supply connection must be used when the
appliance is installed in a location where grounding through
the neutral conductor is prohibited. Grounding through the
neutral is prohibited for (1) new branch-circuit installations,
(2) mobile homes, (3) recreational vehicles, and (4) areas
where local codes prohibit grounding through the neutral
conductors.

What you mean put line to ground can this be done? could u explain what are those wires for?


1) No you don't put 'line' to ground in any application.
But people use the word 'line' to describe a cable or a wire.
So your question is not clear, or maybe an answer you got from someone is not clear.

2) Let's go over wiring for T104 timer.
You posted under T104 Intermatic 240V timer.

3) Electricians use the words 'Line' and 'Ground' to mean specific things:
Line wires are wires that come from breaker box and go to timer.
Load wires are wires that leave timer and go to Load (light, fan, motor, pump)
Ground wire is extra safety line that is bare copper or green insulated wire.

4) How to wire T104 240Volt timer:
http://waterheatertimer.org/How-to-wire-T104-Intermatic-timer.html

Line wires from circuit breaker connect to terminals 1 and 3.
Load wires going to Load (light, fan, motor, pump) connect to terminals 2 and 4
Bare ground wire connects to green ground screw.
Terminal A does not have any wire in typical 240V connection. So terminal A has no wire.

5) If your power is 120V, then T104 is not the right timer.
You might need T101 or T103 depending on what you are doing.
Add a comment if needed.

6) If you have a different timer than T104, add a comment with specific brand and number that shows inside timer door. I have wiring diagrams for most box-type timers.

Add a comment for more free help.
Also take advantage of fixya phone service.
For a price, expert speaks with you over phone while you work on timer or any do-it-yourself project.
Fixya is always less expensive than a service call.

Do i need to hard wire a single oven


Hello,

Welcome to FixYa.

You don't HAVE to hard wire, you can install a regular oven plug and receptacle outlet, but this is the recommendation of Bosch.

**Before installing the oven have a qualified electrician verify that your home is provided with adequate electrical service and that the addition of the oven will not overload the branch circuit on which it is to be installed. A separate three-wire or four-wire single phase, 240 Volt, 60 Hz., or a 208 Volt, 60 Hz. branch circuit is required.**

yes your ok if they say the unit doesn't need to be changed in the incomimg power from 208 up to 230 volts or vice-versa,normally they classify motors as120/208/ 230 /460 volts, instead of 120/240/480 volts,but all line voltage varies in this voltage range between 230 to 255 volts a.c. with a +10/-10 percent tolerance either way,and as long as the instructions dont say anything about changing motor connections your good to go, just look on the motor body if possible and make sure theres no wiring diagrams to change voltage,but i would say no in a package A/C like that, and as far as the current goes your good with the 20 amp tandem pole breaker,let me know if i can further assist you. thanks

I'm trying to install a new Fahrenheat 240/208 baseboard heater and it trips the circuit. The old heater was the same 240/208. I initially thought I had miswired the heater but it tripped the circuit...


Hi!
If the circuit breaker is tripping instantly when power is applied to the heater then you have a dead short somewhere. You need to check your wiring again. Either it is wired wrong or you have part of a bare wire that is touching another wire or to ground. If all your wiring is correct then the element could be bad or is grounding out to the cabinet or whatever. Take another good look at all the wiring. Good luck!

Install and hot wire heater


You can be assured that the element is 240 volt. The fan motor is also rated at 240 volt. the wires you have black - black are the connections you make to the line. Use a 12/2 with ground. Use a double pole 20 breaker in your panelbox. The green wire is the equipment ground - connect this to the bare wire from the 12/2. On the 12/2 cable - there will be two colors, one black and one white. Wrap a couple of turns of black tape on the white wire both at the heater location and on the white in the panelbox. connect the 12/2 to your 2 pole breaker, the black wire and the taped white to the breaker.

Wiring installation


You do need a 208/240 volt supply from your service panel. The green is ground, white is nuetral, and the red and black should measure 120 volts each to ground or 240/208 between each other. It is normal for most breaker panels to supply 208/240 between adjacent insulators. If you are only getting 1/2 of that then the circuit breaker may not be straddling the insulator bar but be 1/2 notch out and both breaker pins contacting the same 110 supply.
