What is meant by a 'dead front' switchboard?
AI Explanation
The correct answer is A) a switchboard with insulated switches and no exposed terminals.
A 'dead front' switchboard refers to a switchboard design where all the live electrical parts, such as switches and terminals, are completely enclosed and insulated, with no exposed energized components. This design helps to improve safety by preventing accidental contact with live parts, reducing the risk of electrical shock or arc flash hazards. This is a requirement specified in electrical safety regulations for marine and industrial switchboards.
The other options are incorrect because: B) a switchboard without safety handrails or rubber mats is a separate safety requirement, C) a switchboard without circuit breakers would not be considered 'dead front', and D) a switchboard without switches would not serve its intended function.
