What PPE is required when checking fuses in an MCC bucket?

• A. Eye protection only
• B. Flash & Shock protection; follow the label on the MCC if present; otherwise Table Method (PCP-650 or NFPA-70E)
• C. No PPE required
• D. Hearing protection

Answer: (B)

Working on fuses inside an MCC bucket exposes you to arc flash and shock hazards. To protect yourself, you need flash protection (arc-rated clothing, face shield or hood, safety glasses) and shock protection (voltage-rated insulating gloves and insulated tools as required). If the MCC bucket has a label specifying PPE, follow that exact requirement because it’s based on the device’s specific incident energy. If there’s no label, use the Table Method from NFPA 70E (or the PCP-650 approach) to determine the appropriate PPE based on the expected incident energy and the task. This combination of protection addresses both the potential arc blast and the shock risk; eye protection alone or no PPE would not be sufficient.
