Spacing of DC Shunts at 400VDC
Spacing of DC Shunts at 400VDC
(OP)
I'm currently designing the layout of a DC Shunt panel,
can anyone tell me what the minimum gap should be between the exposed copper at 400VDC? or is there a chart somewhere that can tell me...
Cheers

Lacking a more specific reference, something conservative like 99NEC374-7 may do. Bare conductors shall be securely and rigidly supported so that the minimum clearance between bare current-carrying metal parts of different potential mounted on the same surface will not be less than 2 in. (50.8 mm), nor less than 1 in. (25.4 mm) for parts that are held free in the air. A clearance not less than 1 in. (25.4 mm) shall be secured between bare current-carrying metal parts and any metal surface. Adequate provisions shall be made for the expansion and contraction of busbars.
