I have service going to a pole, then down to a meter base with a breaker. Power will then be brought back up the pole and then overhead over 2 poles (house is 110 ft from service). Iv done fiber optic wire before (different job) and at each pole we used a clamp method with the messenger wire.

Can i use this clamp on the messenger wire at each pole and use all thread through the pole to attach or will that compromise the "neutral wire. Any suggestions on what else i can or should use. yes it has to be over head.

 

Technically it will be the ground wire since you will need a four wire feed after panel on the first pole.

 

The area inspector has told me that if Fortis supplies the meter base and breaker then I only require 3 wire but if we supply the meter base and breaker we need 4 wire. Fortis has been supping the meter base more often for rural customers.

 

Suspending service cable requires some considerations. Most aluminum service cables are not rated to be hung. You would need to get triplex cable which has a steel runner in with the bare neutral.

To utilize your method with those clamps would require you installing a guy (runner) wire first.
When I suspend triplex I use service hooks and wedge clamps.

I am assuming that you are saying that the inspector has said that if the utility supplies the meter socket with breaker than you follow the National Electric Safety Code and if you supply the meter socket with breaker you follow the National Electric Code. The way I see it is that if you supply and install the wiring after the breaker you should follow the National Electric Code which says this is to be a 4-wire feed to the subpanel at the house. Regardless of what I think, you need to follow what the inspector wants to see, but I also think you have a good argument for using a 4-wire feed.

 

I also normally use the wedge clamps like PJ posted and insulated knobs with a lag bolt.

Fortis uses a "non approved" breaker ( not sure what that means). whereas if i bought a meter base with breaker it would be " approved" and i would need 4 wire for it. Also this install is in Alberta so CEC is the rule of law.

 

does anyone have a picture of this in use.

 

OF the breaker or the knob?

 

knob, but i went for a ride in an older neighbourhood and found kind of what i was looking for. thanks

 

That is actually what I was going to suggest. 😊

 

You didn't tell us this was in another country, all bets are off. Follow what your local inspector tells you to do.
