I haven't done a temp service in a while, as most jobs we've used a generator for temp power. Have one where the customer wants a temp service. The permanent will be 3" PVC. The house will be a modular, so the meter socket can be mounted to the house as soon as the pieces are set on the foundation.

How would you guys handle this? Would it be just set a temp board and mount a small temp panel? I was thinking of having this, and initially just running extension cords. After mounting panel in basement and brining in HR's (that's what the HO claims is the way this things coming in - I have personally never been involved in a modular), I was planning on back feeding the panel so we can get some lights and the furnace going. This job is going to happen when things will start to get cold around here.
 
Hi Dave-- long time

I haven't done a modular in many, many years. Around here we as soon as the modular is in place we hook up the conditional permanent power. In other words they will energize the service equipment.

If there is other work to be done they will ask us to disconnect the lighting and all other non gfci circuits. They will allow the heat and a/c to be connected if the system is finished.

I am not sure why they would need temp power if this is a modular unit. Is it to build steps , etc? If so I would contact the local inspector and see if he/she will accept the type of install I suggested.
 
Dennis - long time and thanks for the reply. So if I understand your post correctly, they won't let you hook up the GFI and lighting circuits in the modular home, only the heat and A/C - is this correct? If so, what is the logic?

No--- they will let you hook up the gfci circuits so that you can use them for any construction. Since the house is finished (technically, they may give permanent power but some jurisdictions may not until all the construction is finished .

They obviously don't want workers using tools without GFCI protection.
 
Temp Service

The reason for a temporary service is because some modular's take awhile to install. For instance if its going on a basement or building a garage. Then you have power to wire the basement and garage and you can wire temp heat if the HVAC has been set. Sometimes it takes awhile to have them set. Also it takes awhile to wire the two units together and you can't set the meter base yet.
I responded to Dave privately before this so I wouldn't have to defend myself on the form. I didn't have the extra time. I sent this in response to your questions Dennis. Have a GREAT day and Semper Fi. Buddy
 
Sounds like the temp service is going to be on the permenent house if I am understanding. Why not just install the permanent service?

I just put a service on a house last week. I won't be roughing it for another week or two. The frame went up, the service went on. There is now power on the site and no more generators.
 
Depending on the power company, the "temp" service can be located adjacent to the permanent one, or out by the street next to the pole or transformer.

We are in an area which has more than one power company, depending on whether you are out in the boonies, or in town. The rural coops allow you to place your temp pedestal adjacent to the final meter location, and they use the same feeder cable for both the temp, and permanent services.

The in town guys prefer a separate temp service located out by the transformer or pole, and they install a separate line for the house. Both services can be energized at the same time with this scenerio.
