When taking voltage measurements, for reasons of electrical safety, what should be the proper sequence of actions?

Correct Answer: Option C — First, determine the nominal voltage from the nameplate. Next, select the proper PPE and voltage tester to use based on this nameplate voltage. Finally, take voltage measurements with confidence.

Safe electrical work practices require personnel to first identify nominal system voltage from equipment documentation, enabling the correct selection of rated PPE and testing instruments before verifying zero energy state on marine switchboards.
