"Pedistal" basically means it's supported only at the bottom.

Here's the closest image I have.... a 200a mobile home pedistal.

I'd put little faith in what the POCO or inspector told the owner. Things like that have a way of getting translated from "The spirit is willing but the flesh is weak" to "The wine is great but the meat is rotten." :D

I have also seen and herd pedistals called meter raceways by the poco.
I herd many just call em underground meters.

Being suported only at the bottom I agree is what a meter pedistal is listed for in a catilog.
I also seen something that was more of a square combo box free sitting. A catilog showed that had a transformer, meter, and disco. I see something like that around street corners and am guessing it's for street or traffic lighting.

I think trade slang is not as accurate in meaning. I have also herd and seen the term meter pedistal used to describe a pedistal mounted on a building.

I have not seen anything called a pedistal mounted inside a building. The problem I see with using a pedistal or undergound raceway meter is the bottom cover is designed to be partially burried underground. If it is burried in cement the bottom cover will be unaccesable without breaking the floor. I want to say the bottom cover will block the poco lugs.

Like said talk directly with the poco and inspector to see exactly what they want. Make sure it's drawn up on paper on how it will be done and approved by everyone involved first. Many times the poco will have a guideline / rule book with details of what they want. Meter socket manufactures have different catologs for different areas depending on what is approved by who. Things such as a CT cabinet for 3ph 400 amp and above. Some places want main discos outside while others want inside.

I always hear the term and think of underground conduit stubbing up to a small slab on which rests the transformer. In your instance, I'm thinking "housekeeping pad" or a raised from finished grade slab on which to mount your service.

I'm nobuilding code expert but I've always understood it to be that you have to lay blocks or bricks staggered, and that it's not a matter of aesthetics, but more a matter of that's the more structuraly sound method.


No not if they are core filled and have some steel rod they will be just as strong if not stronger. think of the mortar as glue. like a glue joint on wood is stronger that the wood most mortar joints are stronger than the brick or block they hold if done correctly. remember I am not talking about a veneer brick face with mortar.

The block work in the photo is referred to as a "stack bond" where the CMU's are stacked rather then laid staggered. When the blocks are laid staggered it is called a "running bond" Both are equally good as long as they are installed correctly.

From my favorite dictionary: http://wordnetweb.princeton.edu/perl/webwn

Noun

  • S: (n) base, pedestal, stand (a support or foundation) "the base of the lamp"
  • S: (n) pedestal (a position of great esteem (and supposed superiority)) "they put him on a pedestal"
  • S: (n) pedestal, plinth, footstall (an architectural support or base (as for a column or statue))
Take your pick, All I could think is that your going to elevate and build a structure for it ...

We're just outside of Chicago and installing meter pedestals on houses is extremely common. We just shoot the pedestal to the foundation, run a 90 degree EMT elbow out of the back of the pedestal, over the basement foundation wall, into the top of a panel in the basement, install our feeders and were done. The utility company trenches to the pedestal, they lay their wires in the trench, up into the pedestal and then make up their terminations.

What's nice with this setup is that we can install the service as soon as the basement foundation is back filled. That means that there is usually permanent power to the house when we get in to start our rough.
