Home / Spacing between wires in distribution boxes
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. Some of the requirements and ratings include: voltage, continuous current, wire range (load and line side). Choose the right box based on environment (indoor/outdoor), load capacity, and durability. Ensure safe placement: install in dry, accessible areas with good ventilation and at appropriate height (typically ~1. Copyright © 2008 by the Institute of Electrical and Electronics Engineers, Inc.
