UL508A contains two important requirements to consider when applying power distribution blocks. Spacing of 1 ̋ through air, 2 ̋ over surface (at 600V) is required when used in a feeder circuit (that's everything ahead of or on the line side of the final branch circuit overcurrent. Working space: The front clearance, side clearance, and height clearance requirements for electrical equipment that provide a safe area for maintenance, inspections, and other work. Dedicated space: The space equal to the width and depth of electrical equipment in addition to the space extending. When applying Power Distribution Blocks (PDBs), there are various requirements that shall be satisfied, based upon diffe...
