The clearance may be reduced to 1 foot if the height of the wall does not exceed 2 feet and if the wall thickness does not exceed 1 foot (i.e., planter box). FM Global has detailed transformer installation requirements I've used in the past. Working space is not required in back of assemblies such as dead-front switchboards or motor control centers where there are no renewable or adjustable parts such as fuses or switches on the back and where all connections are accessible from locations other than the back. Jul 25, 2003.
