ABYC ELECTRICAL EXAM 2026
CERTIFICATION ASSESSMENT BLUEPRINT
VERIFIED SAFETY SYSTEM
◉ a. 15 amps
Answer: How much current should flow through the DC grounded
conductor in a 15 amp DC lighting circuit?
a. 15 amps
b. 0 amps
c. 10 amps
d. None of the above
◉ b. Technician B
Answer: Two technicians are discussing increasing the number of
traditional lead-acid golf cart batteries on a customer's vessel from 4
to 8. Both technicians agree that batteries have to be accessible for
inspection and maintenance according to the NFPA. Technician A
says that the batteries must be in a vented box and secure.
Technician B says that boxes are not necessary and a sealed
composite tray matching what the boat already has would be fine
and looks better. Who is correct?
a. Technician A
b. Technician B
,c. Both A & B are correct
d. Neither
◉ b. 8 AWG (using E-11 Table IX, 3% voltage drop, 40' total distance,
10 Amps)
Answer: You're installing a 500 GPH bilge pump to be used as a
shower pump (just to drain the shower grey-water). It draws 8
amps, is 20' from the distribution panel, and operates at 12 volts.
Using the ABYC voltage drop table, what size wire is needed?
a. 14
b. 8
c. 10
d. 12
◉ b. 12" (see E-10.7.8)
Answer: What is the closest distance an unshielded metallic fuel
system component can be to a battery terminal?
a. 8"
b. 12"
c. 16"
d. 24"
,◉ d. When installed immediately under a split lock washer and nut.
(see E-10.8.5)
Answer: When can a flat washer be used on a battery terminal?
a. When it has a resistance of less than .01 ohms
b. When installed immediately under a wing nut
c. When installed in between the base of the battery terminal and
the conductor terminal.
d. When installed immediately under a split lock washer and nut.
◉ a. Isolate the grounding system from the main ship grounding
system. (see E-30.5.2)
Answer: When grounding an electrical propulsion system you
should always remember too...
a. Isolate the grounding system from the main ship grounding
system.
b. Install a blocking diode between it and your main ground bus.
c. Tie your ground into your bonding system.
d. Combine it with your main grounding system.
◉ c. Checking voltage drop when engaging starter motor (Calder p.
78)
Answer: Of the following which is NOT a correct way of testing a
battery.
a. Use a load tester
, b. Keep track of amps going in and out with an amp hour meter
c. Checking voltage drop when engaging starter motor
d. Measure open circuit voltage
◉ B. 90 min
Answer: The minimal battery reserve capacity in minutes for a
supplied battery power, based on ABYC.
A. 30 min
B. 90 min
C. 120 min
D. 200 min
◉ d. hydrogen
Answer: A gassing battery gives off:
a. sulfuroxide
b. nitrous oxide
c. nitrogen
d. hydrogen
◉ c. 12.7
Answer: A fully charged battery, at rest will have a voltage of:
a. 12.2
