I may be dumb but does anyone know what a 4" standoff is as referred to in this diagram from the power company?

Thx.
 
Some poco's stand all of their riser conduits off the pole. Why they do this I have no idea (tradition perhaps.) Many (most?) utiliites in my observation just strap them right to the pole with rigid 2-hole straps.

It'll be a 2" EMT conduit riser. Are they referring just to Mineralac hangers?

The pole feeding my house has 4" standoffs. Looks funny.
 
As sad as the drawing is from a drafting edicate side, I can only assume its a trade practice or suffers from the lack of a checker.
 
Putting 4" between the riser and the pole will only force you to do an offset to get into the hub.

I'd just put in Minnies and call it good.

The acceptable type and method of the standoff should be in their specs, and it will be very detailed.

I'll call him in the morning but I just wondered if it was a common thing, perhaps not. The only difference in installing a service on this pole is that it has a transformer. We usually put them on customer poles that have no transformer and use Mineralacs.
Thx.
 
Our Poco requires 7".You are NOT to attach ANYTHING to their pole.

I got a lesson from the Poco's lineman how dangerous electricity
was when I upgraded my panel a couple years ago.I had
no idea there was danger involved.If I had known I would've
hired a Handyman to do the work.

I've never seen that. Do they make a device or do you have to prefab something?

That must be to allow the risers to expand and contract from all the cold and snow that you get.

Hey it snows two hours from the beach at Big Bear who knows it might
drift west and break all our risers! It does get 40 degrees at night
in the DEAD of winter you know.You ever suffered from a 40 degree
winter? Yeah you think YOU have it rough!

I prefabed a uni-strut rack and they MADE me remove it.Polietly
told me to NEVER ATTACH ANYTHING TO OUR POLE.Then attached there
uni-strut rack.Witch was identical to the one I made.I even welded it
instead of using L-brackets.

That's because you're taking work away from them. ;)

Here, we strap the first 10' (RMC) to the pole, and they do the rest up the pole. We have to pull the service lateral too. This is National Grid aka National Squid aka National Greed.
 
Our POCO requires 12" standoffs, first one buried, next one at 7 ft, so the riser does not become a ladder.
We use Fetter Point lags 1/2 x 4 to install, they are a drive type lag screw with one way threads; much better than standard lags. Take a big linemans hammer and bash them in.

Yep I had to give them 7' as well my lags for the rack was 1/2x4 too
but not the Fetter.MIne was Hammer then socket wrench.I think
that's where I was wrong I did'nt follow the standard of
"If you don't BASH they won't last" rule.
 
Just curious....Why the large standoff?

I can understand a couple of inches...but 7" or 12"....seems like overkill?
