CFR 1926 requires GFCIs on all what on construction sites?

• A. 120 volt, single phase, 15 and 20 amp receptacles
• B. 240 volt receptacles only
• C. All outlets indoors
• D. Outdoor receptacles only

Answer: (A)

The main concept here is that GFCI protection is required for the common 120-volt electrical outlets used by workers on construction sites. Ground-fault circuit interrupters quickly shut off power if current leaks to ground, which can prevent fatal shocks in wet or damp conditions or when cords are damaged. The best answer is that GFCIs are required for 120-volt, single-phase, 15-amp and 20-amp receptacles. These are the standard outlets used for most tools and lighting on site, and the protection applies regardless of whether the outlets are indoors or outdoors, as long as they’re 120V and within the typical 15/20A circuits. The other options don’t fit because 240-volt receptacles aren’t covered by this specific requirement in the same way, and the rule isn’t limited to indoors or to outdoor receptacles alone.
