Great pictures. In the first one, I wonder if the POCO thinks the meter reader has easy access to the meter.

In the second one torpedo level comes to mind. [Linked Image]

Like Roger said, great pictures!

Are they going to raise the grade all along the side of the house, or is that it?

Maybe they should leave the scaffold there for the meter reader. [Linked Image]

Or put a railing up ...

Thats the finished product Bill.

The retaining wall is constrcucted on the property line. One of the many challenges faced when you build on the mountain.

I red-tagged the job and cited working clearance. The gaurd rail is an option, but I really don't want that panel right there.

Question: How does the NEC address the surface of the required working clearance? Is it silent? Can you stand on jagged boulders? Hmm....

Ryan,

I don't know any code section that requires solid footing in front of equipment. I thought about making a proposal on that for the 2005 NEC, but didn't get around to it. It should be common sense I think.

If there was such a rule it could also affect Panelboards and equipment installed in stairways.

Bill,

Ryan I don't se working clearance as an issue here. As Bill said there is nothing about working surface. I don't think you could fail this. The poco may have the authority to disallow this (maybe won't energize?) if it does not conform to their specs.

Ryan,

Is there nothing in the Building Code about guarding from falls, etc? If I put in a small fish pond on my front lawn that is 12" deep I'd have to put a fence around either it or the whole yard with a self-latching gate.

Maybe the POCO would have something to say if you point out the possible danger to their employees.

How does the local building code treat the edge of the yard at the top of the retaining wall? Are you allowed to roll a car, un-impeded, over the edge and into the neighbor's yard?

What about 6'7" maximum to the OCPD.

And isn't the idea of 3' working clearance that you can step back 3' from the equipment?

Unless you feel like taking a fall you can not step back 3' here.

Ryan, Along the lines of Bill's and Al's post.

I can't tell for sure but it appears as though there is a crevice between the two levels.

If a person (especialy a child) were to fall could they be trapped?

I agree with Bob that the three foot clearance should be a flat surface.

whether specifically written into the code or not, our local inspectors require a flat unobstructed surface for this area.
