Temp For New Building

[Alwayslearningelec]

Not sure if this would be different answer geographically.
Utility service is coming in underground.
Haven't looked at new construction building in a bit.
Need to setup up temp power service for 2 story building.
What are the options on where to get power in the very beginning?
I'd imagine the utility would have provide some sort of incoming power right away??
What would be more practical, setting up a temp switchboard or using the permanent as temp?

It would be a good idea to request a meeting with the local power companies engineer.
They used to come out right away when you called. It seems they have a longer wait time now.

Anyone else offer an opinion?

99% of the jobs I see need temp power long before the service gear is installed and before POCO has installed their infrastructure for permanent power.

You’ll have to call the utility and ask what they can offer. It’s unlikely you’ll be allowed permanent service before the building is ready.

The other issue is transformer lead times. I’m still seeing 60/wks from the utilities here. If they have overhead infrastructure in place, it’s likely they can build a pole-mounted bank and run underground to a tap pedestal.

I’ve been either setting an overhead pole at the bank, or wait for them to set the pedestal and connect an underground temp pole. It’s ultimately up to the serving utility to decide.

Start by contacting the utility co. (PSE&G, JCP&L, etc)
Marketing Dept, and then Engineering, or the area wiring inspector.

You should know a NJ Lic. EC, and they should be able to give you valuable assistance, based on their experience.

IMHO, forget the temp from the permanent like your sketch.

Buy a generator. Send generator to auction once project is completed (this is usually cheaper than renting as long as you have somone to do maintenance. Get the equipment operators to keep it fueled)

Is this ConEd? They will tell you where the incoming power is available in the street and where to install the sleeves in your drawing.

It might be better for the o.p. to consider a dedicated temp entrance. Using the spaces for your one line with temp power always (may) screw things up down the road..
We always run straight into the data rm w/pipe and rated temp cable and put our pedestals in the idf.
Dont block your progress w/temp crap... Let the data guy deal with it, since they always show up last.

Depending on the project temporary power can be a large item. For example, along with the 120/240 we have had to provide 480 three phase for tower cranes for multi year jobs. There was a few meetings with the POCO's before the start.

A 2 story building would only use a mobile crane...

That's right. Then if you install a temp elevator the state inspector has to check it.
