 OK here are some pics of my elect panel installation on my metal building workshop. From top left, going clockwise. I has some wasted space between the man door and the 12wx14h glass garage door, so this was the perfect place for the meter outside and the panel inside. Looking at the side of the meter socket, you can see it is spaced off the building. I used four 3/4 galvanized pipe couplings to act as spacers and ran bolts from inside the box thru the spacers, thru the wall, thru the insulation blanket inside, and placed a neatly cut piece of 3/4 plywood inside for the bolts to pass thru and tighen up to. On a metal building there is nothing solid to mount the meter can to, and I used the 3/4 plywood inside, edges rounded with a router to eliminate the sharp edges and placed reinforcing tape on the insulation blanket and squeezed it all together. It works well. The meter can has a 200 amp breaker disconnect in the RH half of it under an access door. This is a 200 amp Siemens meter socket/disconnect. The 200A/40 circuit panelboard is mounted on a piece of superstrut running from a floor bracket to the 7 ft purlin and steadied with a piece of the thin superstrut running horizontally from one C channel column to the next. Behind the panelboard you can see the white painted plywood reinforcement on the insulation with the bolts/nuts in the corners, retaining the meter socket/disconnect outside, and the large grey PVC conduit connecting the two. Here is the open panelboard. I used a main lug panel as the disconnect was only about two steps away outside. Had it been many feet away, I would have used a main breaker panel, but this is cheaper, and has more room in it to work. This is a Siemens 40 full space panel. The two devices in the upper left slots are surge suppressors with LED indicator lamps, the breaker just below it feeds a subpanel that the air compressor is connected to. I took advantage of the superstrut to install a 50 amp welder outlet, a 20 amp 240v outlet, a 20 amp/20 amp receptacle, and a double receptacle box. I have 9 20 amp breakers feeding 29 duplex receptacles throughout the building. The side by side receptacles, in all cases, are on different breakers, and I carried out individual neturals for each circuit though I didn't have to. The two circuits could share a netural if wired in a proper multi-wire circuit installation. The empty 4x4 boxes are for light switches, I haven't installed the overhead conduits yet. Presently the building (a 60x60 aircraft hangar in my back yard) is lit with two 500 watt quartz floods mounted on the 12 ft purlin on the west wall. Provides decent area lighting at nite. Sorry for the small pic size. I need to find a pic host site and haven't (my web site host will not host pics that are not linked thru the web pages, it blocks an indirect link to them). I posted the pic on the YT Help Identify gallery. Charles
