DC power terminations shall be fully protected with a non-metallic, non-flammable cover.
2.4 DC Connectors
Connectors used to attach the product to external power cabling shall conform to the following
requirements:
2.4.1 8 AWG and Larger Stranded Power Cable
Power input cable that will accept # 8 AWG or larger connector terminations shall use dual
threaded post (stud) termination able to accept the appropriate two-hole crimp connection.
The two post termination may be either 1’,3/4”, 5/8” or 1/2“ on centers. Refer to Table 2-1 for
acceptable connectors.
2.4.2 16 AWG to 10 AWG Stranded Power Cable
