You are in the planning stages of installing an electrical receptacle in a receptacle branch circuit. According to 46 CFR, Subchapter J (Electrical Engineering), under what conditions do the regulations require that the electrical receptacle is to have a grounding pole?
• 46 CFR Subchapter J requirements for receptacle outlets and grounding conductors • Difference between voltage level requirements and personnel safety / accessibility requirements • How grounding poles relate to protection against electric shock
• Look at which of the choices describes a safety exposure for people, not just an equipment characteristic like voltage or AC/DC type • Ask yourself: when would the Coast Guard be especially concerned that a non‑electrician might contact a metal‑cased appliance or tool? • Think about whether grounding is mainly triggered by exposure to weather, by who can use the receptacle, or by the type of current (AC vs DC)
• Check 46 CFR Subchapter J for the specific section on receptacles and grounding-type receptacles—note exactly how it describes where grounding is required • Verify whether the rule talks about voltage thresholds or instead talks about accessibility to personnel • Confirm whether the regulation makes any special distinction between AC vs DC sources for grounding-type receptacles
