You make the call: NEC 110.26

I'm not an electrical guy, but can the dedicated space be measured from the face of the panel? If the panel was, say, 12" from the wall, would this reduce the dedicated space's depth by 12", thus giving you only 24" in front of the panel (I'm guessing that the dedicated space is 36" deep)?In other words, is the depth of the panel included in the depth measurement? This surface mount panel would give you less depth than a "flush" panel at its front.

To restate if the panel is move forward and mounted so as the rear of the panel is beyond the gas pipe then the pipe is behind the dedicated space. That would be compliant IMO.

However in the OP the panel was set first and then the gas line, either way hopefully someone will have a learning experience.

It would appear the electrical contractor failed to determine if the location of the new panel was going to be clear of other installations. If a correction was deemed to be absolutely necessary I would go with Francis Vineyards method.

Doesn't matter who was there first. It is an electrical violation and the electrical contractor is responsible for making his installation code compliant.

From my perspective it is not worth the bother of "correcting".

Would the method of measurement (in my 2005 NEC) for working space be the same as for dedicated space, since there is no method of measuring prescribed for the dedicated space?

Check out the IRC figures; note change adding “from floor” to dedicated space in 2006 IRC (2005 NEC).

Those are good illustrations. Thanks Francis.
