A proposed location for a 112-kVa 480Y/277 dry transformer sus-pended above the working space for a switchboard raises several questions. If the headroom below the transformer and above the required working space in front of the switchboard is 6 feet, 6 inches or more, then the transformer location is acceptable. The transformer does not intrude upon the dedicated space directly above the switchboard, as required by Sec. 110-26(f). The seismic bracing of the transformer, which is suspended on threaded rods, is governed by the building code.
