Called out for a bid on service change. Never seen a right angle meter base adaptor (I guess thats what you call it). Barely enough room to stand in front of panel.

Looks like the panel needs a 90 degree adapter also. smile

If it was easy, anyone could do it.

I imagine no permit on the addition.

That's not a working space violation any more, that's plain old lack of any common sense!

I will say that I've seen those right angle adapters in downtown Fredericksburg, VA where older buildings were built so close together back in the 1930-1950 era. There weren't a lot of rules back then. The existing building was fine, but the new building was allowed to be put up with only two feet between them. The power company used to be a city utility at the time and welcomed any kind of new development, so they didn't dare make existing building owners move their services.

Now that their electric utility has been sold for decades, the current poco has been known to use these adapters since their readers can't fit in those spaces, not to mention the fact that these alleys are full of you know what.

Is the clearance issue really an issue? Some food for thought.

In the 1953 NEC the minimum horizontal working space clearance is given as 1-1/2 feet, measured from the live parts to a not grounded or live surface.

In the 1975 NEC, the same conditions under 600 volts was
2-1/2 feet.

It wasn't until the 1978 Edition of the NEC that it was increased to 3 feet.

Don't know... to me it rather looks like 1 foot and not 1 1/2 but the picture might be deceiving.

As for the age of the addition... the 5 panel door on the addition looks older than the main house, so they might have used scrounged parts... no idea.

He got a point, the version of NEC applies to when it was installed. This what makes code enforcement "fun" crazy
