DC is everywhere and the use is growing.

NFPA 70E addresses DC in Tables such as:

• Table 130.4(E)(b) Shock Protection Approach Boundaries to Exposed Energized Electrical Conductors or Circuit Parts for Direct Current Voltage Systems
• Table 130.5(C) Estimate of the Likelihood of Occurrence of an Arc Flash Incident for ac and dc
• Table 130.7(C)(15)(b) Arc Flash PPE Categories for dc Systems

as well as other areas in the standard.

The Question:

Do you/your clients place arc flash labels on DC equipment?
• Yes
• No
• It depends
• No DC equipment

Your experiences are always welcome!
