What program must a device be part of if a GFCI cannot be used with a portable 3-phase welder?

• A. AEGCP
• B. NFPA 70E
• C. UL Listing
• D. OSHA Safety Program

Answer: (A)

When a GFCI cannot be used with a portable 3-phase welder, the safety approach relies on a formal grounding program rather than a ground-fault interruption device. This is the Approved Equipment Grounding Conductor Program (AEGCP). The idea is to ensure the welding setup is properly grounded and maintained so electrical shock hazards are controlled through correct grounding practices, cable sizing, and verification processes instead of relying on GFCI protection.

This program specifically addresses how equipment is grounded and connected in welding environments, providing a framework that keeps safety intact even when a GFCI isn’t suitable. The other options aren’t focused on this protective framework: NFPA 70E covers electrical safety rules in general, UL Listing is about certification of the device itself, and OSHA Safety Program is the employer’s broad safety plan—none of these alone prescribes the grounding-and-protection approach needed for welders when GFCI isn’t used.
