It's the complete opposite here; you really only see masts for services if the building isn't tall enough to maintain clearance. It's perfectly acceptable here to attach the drop to the building if clearances can be maintained.

Then again, most services here are underground, at least for the past 40 years or so. I guess the mast requirement in California has something to do with earthquake issues?

I actually live in Manassas, Va--the townhouse in Fredericksburg,Va is in Olde Greenwich. I rent it out to my brother.

Interesting that VEPCO saw fit to get rid of those awful pedestals in Springfield but not in Fredericksburg.

What did they end up replacing them with? I looked on a number of websites and it doesn't appear that anyone makes a multi-meter pedestal like that anymore.

They're in really bad shape, being over 30 years old. Let's just say that the meter seal did not need to be cut in order to remove the meter to turn off the power to do my panel upgrade!!!

Not really the mast/earthquake issue, but maybe a little insight:

Overhead service in SoCA is pretty much limited to existing urban areas and rural areas. Anything in a new area is underground. Utilities are in a continuous process of replacing OH sytems and putting them UG. Even a OH service replacement in most areas will be required to have the capability for future underground feed, or might be required to change from OH to a UG lateral to an existing pole. The idea is to NOT do what was done in a couple of areas in the mid/late '70s, when UG started to become the norm.

Our conditions and history are different here than in most other areas. We don't have the issues of ice on OH lines, and lightning is a rarity. OH utilities and service were a natural for us when the place built up like a wildfire. Nobody really realized the magnitude of what was to come. By the time the smoke cleared, there was an OH infrastructure. Great, until someone looked up.

Putting the power and other utilities UG in OH districts is more a matter (besides funding) of disruption to roads and the like than the physical relocation itself.
The effect is somewhat like putting a shovel into an anthill.
There's no heaves or frost line to contend with, so minimum cover requirements up to 35KV can be as little as 30".

Re the pic in electure's post:

I've seen a lot of those "flying gutters" to convert the OH to UG.

I've also seen the remains of a few buildings (and services) when the top of that gutter rots off or is left off..and a bit of rain and watch the fireworks begin!!

RE: Electures pic above.

Is this still an approved method of OH to UG conversion. And are you still allowed to have partially recessed meter pans/stacks??

Boy, this is an oldie smile

I haven't seen one done like this since I took the photo, so I don't know the answer. It would fall under the POCO's rules. It was fairly common during the '70s and early 80's, but just in a few areas.


The semi-flush (partially recessed) meters, and panel boards are the norm here. There are nailing flanges meant to be nailed directly to the studs.

The photo is of a combination Meter, Main, and Panelboard.


laugh Yes, we have have the service masts run through the structure. They are usually GRC or IMC, occasionally EMT.
SE cable is unheard of here. I've personally never seen a piece of it.

CT,

Here in northern NJ I used to see Zinsco quite a bit. They also used ITE, FPE and Murray, and has anyone seen a Wadsworth? ( I believe that is how it was spelled)

I believe that most EC's around here used what ever they could to keep the costs down and win the bids.

Another walk down memory lane...
Yes, Wadsworth.

Also, good old Bulldog Push-a-Matics
Bryant was around, and Challenger

I've only seen Wadsworth panels twice, and once was on a cabin Big Bear, CA wayyy up in the mountains. I found it after we inadvertently plugged 2 space heaters into the same circuit. Breaker never tripped, but made a hell of a buzzing sound after a while.

Bulldog/Pushmatic is fairly common around CA in installs from the 50's/60's (The house I grew up in had Pushmatics and was built in 1958).
