The wire in my house for an elec. garage heater is 14 gauge wire with a 15 amp breaker. I assume i need at least 10 gauge wire with 20 amp .The heater is 20.9 amps and 3000-5000 watts, with 17500 BTUs


Curt, a 20 amp breaker will blow if you pull 10.9 amps from it. I suggest having a licensed electrician do your wiring. Likely, you need a permit anyway.

I have a Whirlpool LER8648LW0 and it will not heat up. I had to change the breakers and once I did that no more heat. Everything else works fine. The only difference in the breakers is the old ones were...


if you had heat in the dryer before you changed anything in the electrical box then i doubt very much it has anything to do with the dryer.if you have a meter you can check at the block where the cord connects to the dryer and make sure you have 240 volts coming to the dryer before you start messing with the dryer

Hi expert: I am installing intermatic P1353me digital pool or spa mechanism and having trouble to figure out how to do this heater Firemen Switch connection. My existing pool timer is T104 and there were...


1) Fireman's switch automatically turns off heater few minutes before turning off pump.
Not all pool timers have fireman's switch.
If old timer did not have it, then don't worry about it.
P1353 has wires marked for fireman's switch, so simply don't use them if you don't want to.
http://waterheatertimer.org/pdf/Intermatic-P1353-manual.pdf
page 21 of manual shows wiring for fireman's switch.

2) T104 and P1353 comparison
Difference 1: T104 turns OFF both hot wires, while P1353 turns Off 1 hot wire.
http://waterheatertimer.org/Compare-120-and-240.html
Difference 2: T104 controls 1 240V load with 1 time schedule, while P1353 controls 3 different 240V loads, each with different time schedule.
Check that wire(s) coming from breaker can handle all 3 loads.
http://waterheatertimer.org/Color-codewire.html

3) 240Volt T104 is wired as follows:
http://waterheatertimer.org/images/T-104-240-Volt-400.jpg
Hot1 from breaker connects to T104 terminal 1
Hot2 from breaker connects to T104 terminal 3
There is constant power on terminals 1 and 3, each terminal has 120V when combined makes the 240V circuit.
Load1 wire connects to T104 terminal 2
Load2 wire connects to T104 terminal 4
Terminals 2 and 4 have power whenever timer turns ON

4) Definition:
In electric wiring, Line means power from breaker, and Load means wire going to light,fan, motor, pump.

5) Converting T104 to P1353
http://waterheatertimer.org/images/P1353-timer-350.jpg
http://waterheatertimer.org/images/P1353-terminals-566.jpg
Hot1 from breaker connects to P1353 terminal 1
Hot2 from breaker connects to P1353 terminal 2
This will power timer electronics and timer clock and switches.

Jumper wire is placed from Hot1 at terminal 1 to each Line terminals 3 5 and 7.
This will put power at the switch, and when switch turns ON, then power will flow from Line wires to Load wires and then on to the Load.
Load 1 connects to terminal 4, Load 2 connects to terminal 6, Load 3 connects to terminal 8
To complete each 240V circuit, Hot2 is connected directly to each Load.

6) You say 'salt' system connects to terminals 1 and 3 on T104, then those wires are carrying constant 240V to that device. So Salt system connects to terminals 1 and 2 on P1353

7) Get a second opinion:
I frequently contact Intermatic for various problems.
P1353 is fairly new product, and manual is long, and I might not fully understand your problem or wiring.
Intermatic answers their email.

I have a Et 70115C Intermatic Timer, I want to install it on my Hot Water Heater, I have connected the 2 110V leads from my breaker to Terminals 1 & 2 and connected the two leads from the hot water...


A) 5 terminal ET70115C.
Voltage selector set to 240.

B) BUT you say you have 120Volts from breaker >>> confusing, so I'm proceeding on basis that you meant to say 240V from breaker.
Add a comment at any time.

C) Review timer:
5-terminal ET70115 timer has NO and NC terminals
NC is normally closed >> this terminal has power when timer is OFF
NO is normally open >> this terminals has power when timer turns ON
For water heater, you want NO terminal 4 so water heater turns ON when timer turns ON

D) Wire for 240Volt water heater

Two hot wires from breaker connect to terminals 1 and 2. This powers timer clock.
Jumper wire connects between terminal 2 to terminal 3. This sends power to the switch circuit.
Wires to water heater connect to terminals 1 and 4

E) 5-terminal timer turns off 1 hot wire to 240V water heater.
Turning off 1 hot wire will stop 240V circuit from working; Water heater thermostats also turn off one hot wire.
240V water heater has black and red wire.
Wire from terminal 4 should connect to Black wire on water heater.

Diagram shows two wires on terminal 1
Two wires on terminal 2
One jumper wire on terminal 3
One wire on terminal 4
Zero wires on terminal 5

There are so many questions. WHAT IS THE MODEL number of the unit that you are wiring The thermostat and the source voltage are two different things. What voltage are you wiring this to?

Hooking up the thermostat


Thermostats are typically low voltage only no more than 24volts that is supplied from the transformer in your heating unit. you need to look at your low voltage wiring that is in the furnace and write down the terminals that are hooked up. Usually (this is a very typical set up) red wire goes to R which supplies 24 volts. green goes to G powers fan motor, white to W terminal and blue or yellow goes to Y terminal this terminal will usually have another wire in its terminal with it to control an outdoor ac unit likely another red or white wire, and lastly the C terminal has a white wire. That is for a basic heating and cooling system just match how they are hooked up at the main unit to the terminals on your thermostat. the thermostat is just a switch breaking and connecting terminals that allow voltage to carry through it. Shut down your unit while working on it as not to blow the transformer otherwise you are gonna need to replace it to if it isnt fused, that is probably my most common repair from people who have tried to change their own thermostat. Hope this helps

What coloured wires go where on the main oven thermostat


If you are speaking of the 240v connection to hook up the oven to the electrical source, then white is the neutral(white to white), black is one of the 240v hot wires(black to black), and red is the other 240v hot wire(red to red).
Finally there is a bare or green color ground wire that goes to the bare or green wire form your source.
normally, the two outside wires on a terminal strip are the hot wires and the middle onif the neutral(white). It does not matter which wire(red or black) goes to what hot terminal at the appliance.
If you are talking about the internal wiring, I can get you a schematic of that.
