Electrician/Refrigerating Engineer (NMC QMED02) is the electrical-and-refrigeration QMED rating, examined in Q802 Electrician and Q803 Refrigerating Engineer — each 70 questions at a 70% pass mark. It covers DC and AC theory, motors and generators, switchboards and distribution, batteries, troubleshooting, and the vapor-compression refrigeration cycle.

Electrician/Refrigerating Engineer is examined in Q802 Electrician and Q803 Refrigerating Engineer. Each module is 70 multiple-choice questions at a 70% pass mark, 3.5 hours long. In the engine-room exam room you may reference 46 CFR and 33 CFR only.
The subject set derives from the Electrician/Refrigerating Engineer column of Table 1 to 46 CFR 12.505(c). We drill each of these areas:

6 months of service in a rating at least equal to Wiper or Coal Passer on the appropriate class of vessels (46 CFR 12.503). Graduates of an approved training ship qualify with no further service, and other approved training can substitute for up to half of the required service.
$280 in Coast Guard fees — $95 evaluation + $140 exam + $45 issuance. You also need a USCG medical certificate (CG-719K), a drug test, and a TWIC (46 CFR 10.203).

Motor and steam propulsion support, lube/fuel systems, pumps and valves, watch duties, and engine-room safety.
Practice OilerThe widest engine-room rating — propulsion, electrical, refrigeration, hydraulics, thermodynamics, and maintenance.
Practice Junior EngineerThe QMED02 exam pairs Q802 Electrician (DC and AC circuits, motors and generators, switchboards and distribution, batteries, motor controllers, and troubleshooting) with Q803 Refrigerating Engineer (the vapor-compression refrigeration cycle, refrigerants, compressors, condensers, evaporators, and air conditioning). Each module is 70 questions with a 70% passing score.
Yes. As of the 2024 QMED rules the endorsement is issued as the combined Electrician/Refrigerating Engineer rating; the older standalone Electrician and Refrigerating Engineer endorsements are now renewal-only. Passing both Q802 and Q803 earns the combined rating.
No. The USCG exam bank has not been public since 2016. CaptainsGround writes original questions calibrated to the Q802/Q803 format and cites every answer to a public source — 46 CFR and public-domain electrical references such as the NEETS series — so you can check the reasoning.
