Question about General Electric G.E. - INDUSTRIAL SYSTEMS TPL412R 125 AMP OUTDOOR MAIN LUG LOAD CENTER

2 Answers

First & Third space in GE TPL412RP are hot, second &fourth not

Just installed 125 outdoor GE TPL412 RP subpanel. Hooked up the 4 wire 240 line from the main panel - ground to one of the two small bars used for circuit grounds and neutrals. Hooked the white neutral to the first large lug, the red wire to the second lug and black wire to the third large lug in the box. Both circuits in the first space are hot, neither circuit in the second space is hot, both circuits in the third space are hot but neither circuit in the forth space is hot. What am I doing wrong?
Thanks
Bob

This is not 3 phase power...you have two legs of 120 ...the red wire? This leg is not a voltage source therefore that wire is not going to fire up that lug ...you only need 3 wires to make this circuit and a neutral is a redundant leg for this box

White t o NEUTRAL BAR
green to GROUND BAR
black to A PHASE (BUSS BAR)
red to B PHASE (BUSS BAR)
4 WIRES FROM MAIN PNL
NEUTRAL BAR MUST BE ISOLATED, DO NOT BOND TO
PANEL
white wires to NEUTRAL BAR ONLY

1 2
BKR A PHASE BKR

3 B PHASE 4

5 A PHASE 6
REPEATS TO BOTTOM OF PNL.

GREEN wires TO GROUND BAR only
Dont forget GROUND ROD,STEEL BOND,METAL PIPE BOND. PROPER GROUNDING = NO 911 CALLS

I have a new furnace and the breaker keeps tripping (20/30). It is a bryant westinghouse box. I think 200 amphes


1) You got a FIRE truck coming.

2) Wire is too small.
Problem is NOT circuit breaker.

3) Both 240Volt appliances on same breaker is a hazard, especially if space available in 200 amp service panel for more breakers.

4) Usually each 240V appliance has separate breaker.

5) Circuit breaker trips because of High heat on the wire.
If wire gets hot, it will start a fire inside the wall.

Electric code requires wire-size match breaker-size.

6) If you put larger amp breaker on same wire that is getting hot, then wire will get hotter.
Result: FIRE truck middle of night with folks jumping out window in glass-cut bare run across yard.

7) Each appliance has volts and watt rating on label.
EVERY appliance has label.

8) For example stove might be rated 8000 watts and 240Volt.
8000 watts divided by 240 volts = 33.3 amps
Stove would require 40 amp breaker and 8 gauge wire.

9) How to figure it out:
http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-install-a-subpanel.html

10) Do same calculation for new furnace.
12000 watt furnace divided by 240 volts = 50 amps.
Use 60 amp breaker and 6 gauge wire.

11) Summary: fixya wants you to be safe, and buy stuff showing in the ads.
Use a bigger breaker ONLY when bigger wire is also installed.
Call furnace installer, the installer should know to check safe wiring before installing.

Plastic clips that hold breaker in broke off


1) If this is for main breaker, then replacement is only option.

2) If this is for 120V or 240V breaker, then move breakers around so you can make space by adding tandem breaker(s) if available.
http://waterheatertimer.org/images/Circuit-Breakers-ap235-500.jpg

3) You can also make space by doubling lesser used circuit onto one breaker, making sure that 14 gauge wire goes on size 15A breaker and 12 gauge wire goes on 20A breaker.
http://waterheatertimer.org/How-to-replace-circuit-breaker.html
http://waterheatertimer.org/Color-codewire2.html

4) You can work around by adding adding subpanel

How do I wire a double pole double throw 240 volt ge intermatic timer to 4 240 volt plugs?


You posted under GE timer, but added the brand name Intermatic.
GE and Intermatic timers are totally different.
Wiring below is for GE and will not apply to Intermatic.

Step 1) lets cover basic GE timer wiring for 240Volt load.
Be sure to set dip switches BEFORE applying power.
Step by step illustrations show on following link.
http://waterheatertimer.org/How-to-wire-GE-15207-timer.html

Step 2) Load wires exit GE timer.
There are two Hot wires and 1 bare ground wire.

Step 3) Wire the outlets: You have 4 240Volt plugs.
This could mean a receptacle-type outlet like a clothes dryer outlet or air conditioner outlet.
Or it could be a twist-lock receptacle or extension-cord-type stage plug.
In all cases, look at screw color on device.
Connect Hot wires to brass colored screws.
Connect ground wire to green screw.

Step 4) Calculate total Load
Manual appears below: Look at Normally Open contacts. These contacts turn ON when timer turns ON.
http://waterheatertimer.org/15087-15207-56922-Manual-eng.pdf
Total load on all 4 plugs cannot exceed 2 HP
Generally, a 30 amp timer is rated for max 24 Amps or 6 amps per each of the 4 plugs.
Volts x amps = watts.
Take total watts and divide by 240Volts to get amps.

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.

How do I run from a 100 amp main panel to a 60 amp subpanel, 125 from my house to the garage


See 60 Amp sub-panel image

Above image shows drawing of 60Amp sub-panel located next to main panel. Drawing shows #6 wire... 125' distance to garage calls for #4 wire. I ran #4 to my barn and have no problems.

Give thought to how many new breakers you want at garage.
See photo of subpanel that holds three 240V breakers

Using drawing as a guide. Replace existing 240Volt breaker with new 60 Amp breaker. Two hot wires connect to new 60 Amp breaker. Neutral connects to neutral busbar.

More space: You can free up space in main breaker box using a tandem breaker. Or by doubling up 2 lightly used 120V circuits onto one breaker. Do not double-up on 240 Breakers

Conduit: You want PVC conduit large enough to fit three #4 wires. Bigger conduit is easier to pull wires ... and maybe later ethernet wire, or alarm wire etc.

Ground wire: You can put a ground rod at garage and run #6 bare copper between sub-panel neutral-busbar and ground rod. Attach ground wire firmly with grounding clamp.

I want you to check with local electrical supply for exact code in your area concerning conduit requirements, grounding, and wire size. Tighten all lugs very tight against wire.

Subpanel hookup


Yes the maximum size branch circuit breaker that will fit in a residential load center is 100 amps. I would recommend that you calculate the amount of power that you need the sub panel to handle, then add any additional loads you may need in the future. Hopefully this is less than 100 amps. I would recommend that you check with your local electrical inspector to make sure your installation meets all local and national codes before proceeding with the install.

Properly installed electric baseboard heater won't work.


I am an electrician. You must measure the voltage across the black and red wires. Measuring each wire to the neutral will not cut it. If both your red and black wire are on the same phase the heater will not work.

To double check your wiring, measure the voltage across the two screws feeding your subpanel, they should be 240v or 208v depending on your power company. Then do the same at the breaker feeding your thermostat. Again it should read 240v.

If you have no potential across the screws it is possible that you installed an incorrect breaker. Not all breakers with two screws on them are 240v breakers. There is what is called a twin or split breaker that has two screws that are on the same phase. These are for wiring two 110v circuits, when you run out of spaces in the panel.

Double check everything. This is a relatively easy circuit to wire, even for homeowners. If the heater does not work them something is wrong so do not leave the circuit energized.
