I am currently preparing to do a service upgrade in an old home in the Boston/ West Roxbury area. The existing panels (2 of them, one for each floor,,,two family) are located across the basement from where an underground service feed enters the building. The area is very congested and my intention is to relocate the panels, to the same side of the building as the feed , and add one more for common areas.
The ONLY place to install the 3 new 150 amp panels is between two basement windows. There are NO obstacles in the dedicated space (depth and width) of the combined area of the three panels. There are water pipes to the right and left of the space BUT NOT in the space. Directly straight out from the panels there are steam pipes but they are 2 1/2 feet out and 6' 3" in height, so there is more than 3' of clearance in front of the panels up to the 6'3" point and then it is 2'5" from the front of the top of the panel to the steam pipe that is enveloped in insulation. Would this be considered a legal installation? I can not find anything stating that it would not be, but I am open to a second opinion.
