What is the correct Depth dimension for NEMA 3R/12 NQ Panelboard enclosures? Is it 6.5'' deep per Digest 176 , Page 9-7 , or 6.25" per the Engineering drawing PBA711 ?
Issue:
Engineering drawing PBA711 shows Depth of MH**WP box as 6.25", and the 176 Digest lists the MH**WP panel box as 6.5"D , which is correct?
Product Line:
NQ Panelboards
Environment:
Plant Engineering drawings
Cause:
Clarification of Plant Engineering drawings
Resolution:
The 6.25"D represented on Drawing PBA711 is correct if measuring from inside backbox to the inside of the front trim.
The Digest 's 6.50" D represents measurements taken from the outside back of the box to the outside Trim/Door , thus the .25" Depth discrepancy.
