DISCLAIMER: ELECTRICITY IS DANGEROUS! USE GOOD JUDGEMENT! ONLY USE A LICENSED ELECTRICIAN TO BUILD AND INSTALL THIS JOBSITE POWER BOX.
If you build or remodel homes for a living you've definitely encountered times when the crews didn't have enough power. This is especially true when you condition your houses during construction. I'm a big fan of Quest Construction Dehumidifiers, Air Conditioners, and Electric Heaters (the heaters run at either 30 or 50 Ams!). Couple that with a 220V cabinet saw for my finish carpentry crew, several miter saws, two compressors, and a half dozen makita chargers and you can quickly max out a small temp power service!

Here's the parts list you'll need to make one for yourself. It's going to run about $1000-1200-ish for the parts but this power panel should provide many years of use. Tim Hill my Project Manager made this parts list for this particular panel box:
2- GE 125Amp / 16 circuit surface mount Main Lug Panel
6- 2 gang Bell boxes
3- single gang Bell boxes
2- 2 gang Bell box covers for single 14-50 Receptacle
4- 2 gang Bell box covers for 2- 110 V duplex Receptacles
3- Single gang Bell box covers for single 220 V Receptacle
1- "14-50" Receptacle (range plug)
1- "6-30" (heater plug) or "18-30" (dryer plug) Receptacle (depending on equipment needs)
8- 20Amp 110 V duplex receptacles
2- 20Amp 220 V receptacle
1- Leviton combination 110V / USB receptacle
1- "in-use" single gang flip-up cover for combo receptacle
1- 2 pole GE 50 Amp GFCI breaker
1- 2 pole GE 30 Amp GFCI breaker
2- 2 pole GE 20 Amp GFCI breaker
4- single pole GE 20 Amp GFCI breakers
1- single pole GE 15 Amp GFCI breaker
2- single pole GE 20 amp "thin" breakers
1- Whole house surge protection device
100' 1" Carflex non-metallic liquid tight conduit
Fittings for conduit to panels
110' 4 ga. 3 conductor with ground aluminum "service entrance cable"
Lastly, you'll want a 45 degree position hand truck to make it manageable getting to/from the job site and to set it up onsite.

|The labels help to quickly identify the plug you'll need.|
|We mounted it on a piece of 3/4" plywood and covered it with some leftover Tyvek Flexwrap for longevity.|
|These 220V plug are for our portable dehumidifiers and air conditioners.|
|The 50Amp 220v is for our Quest Electric Heater. I don't like propane inside the house, and I don't like running the clients furnace.|
|Be sure to give yourself plenty of 20Amp 110v plugs!|
|Your subs will love being on your jobsites if you provide this kind of power!|
Let me know if you build one, and I'd love any tips/tricks you've found with temp power for your job sites.
