Hold-down bracket for an electrical terminal block

An electrical terminal block assembly for support within an electrical enclosure comprising:

• an elongate terminal block housing having a raised planar surface including a plurality of openings therethrough arranged in plural staggered rows and a perimetrical sidewall extending from said planar surface forming a bounded chamber;
• plural terminal modules extending through said openings, said modules having first electrical connection means above said planar surface and second electrical connection means extending below said surface and into said bounded chamber;
• a cured potting compound filling said chamber and covering said second electrical connection means;
• and
• a hold-down bracket for supporting said terminal block against a surface of said enclosure, said hold-down bracket including an elongate body having securement means at one end thereof for mechanical securement to said surface of said enclosure and terminal block holding means at said other end for supporting said terminal block with respect to said enclosure surface, said holding means further including an elongate tongue configured to be inserted from above between adjacent terminal modules, said tongue having a widened end portion preventing lateral withdrawal of said tongue from between said terminal modules.
