Temporary Service


This is a page that isn't offered to many. The reason is because each area is different (Provinces) and each local utility has a different way of doing things. I'll show you the Nova Scotia temporary power accepted practice. There are of course different ways to do things, and there will be different people doing it different down the street....we're merely showing our way.

Here is the link to Nova Scotia Power's guide to temporary power.


Let's break it down......

If you'd like to see a complete list that you would need from the electrical contractor, select this link and print it off.

The first thing you need is wood.
Usually it's got a base of 2 - 2 x 4's or 1 - 4 x 4 so it'll hold the service, conduit and masthead. Then there are 3 more 2 x 4's that form a tripod or triangle. Here is a picture so you can see an example.

The one shown above is buried three feet. There is also a variation that can rest on the soil....but it takes more wood and is supported from all sides. This is shown below.

This one is literally made of 2 x 6's but it isn't buried. So to make up for buried strength, it's made of sturdy wood that is secured at each 90 degree angle. Making it a topical temporary service.


This portion of the page will show you from top to bottom what to put together piece by piece.

1 - 1 1/4 inch PVC Entrance cap

1 - Heavy Duty Porcelain Insulator


1- 10 foot length of 1 1/4 inch PVC conduit

4 - 1 1/4 two hole straps PVC


Heat about a foot from the end of the PVC that goes into the hub, with a heat gun, so that it creates a small offset to stay flush with the wood. Be careful to back off the heat gun so it doesn't burn the pipe. As a rule we all try to hide the PVC markings when installing.


1 - 1 1/4 PVC Meter Hub (Unthreaded)



1 -100 amp combination meter socket panel. Ring Style. Depending on your construction needs, this can be anywhere from 30Amp to 70Amp. This is just a conversation with the utility and your inspector regarding usage.

Insert 2 Black Wires and 1 White - #2 Nual service entrance cable (RW90) from the panel, through the meterbase and up to the mast. Leave a minimum of 750mm or 2.5 feet for drip loop. The linesmen need to connect the service, so leave them plenty.

The one shown above has 4 breakers that are not GFCI breakers. There are two GFCI receptacles. The 20 amp receptacle shown to the left is not GFCI protected. This is against outdoor usage CEC code and Nova Scotia Power temporary power requirements. In order to meet code, you can remove the breaker and just install a filler, or you can put in a GFCI 20 amp breaker. The code clearly states that it has to be GFCI protected. Whether that be by receptacle or breaker....either way meets code.


Noalox is an anti oxidant that has to be used on all service conductor connections to the meter and panel. Very important.


2- 1/2 inch PVC male terminal adapter



1- 1/2 inch PVC conduit (10 ft) You won't use it all, that's the smallest increment you can purchase.


You branch off of the panel and come down with two conduit raceways to wire from the panel to the pvc receptacle boxes. Cut them about six inches in length. Put the male terminal adapter (TA) end in the panel, cement in the 6 inch pvc pipe in female end of TA, and cement in the other end directly in the PVC receptacle box. You can use painted plywood to mount your two boxes. This is a matter of your own preference.



2- PVC FSC Single Gang Outlet Boxes


2 -Extra Duty While in Use Receptacle Covers

Insert one black, white and one green stranded #12 (THHN/THWN) (CEC Table D1 Appendix D) wire to go from the single pole breakers in your panel, through the 1/2 pvc conduit, to the receptacle pvc outlet boxes.


Make sure your connections are nice and tight. Loose connections arc, especially in wet locations. The receptacle cover has to be extra duty.


A #6 green copper attached to the neutral bar in the panel and attached to a ground rod pounded into the soil, or a ground plate. Make sure the clamp will accept a #6 conductor and the ground rod.


1- 1/2 inch strain relief connector stainless




1- Ground clamp




1- 3 meter Ground rod, driven the full length of the rod. According to our Nova Scotia Power 4.23 Bulletin we can use 1 ground rod.

Or....

1- Ground plate. Under soil, no less than 600mm or 2 feet.
