◉ What should be checked for charger output to the battery?
Answer: Check battery open circuit voltage and then check for a
voltage rise of 0.5 V DC or more.
◉ Can AC and DC run together down the same conductor?
Answer: Yes, according to Tech A.
◉ What is important when installing an inverter in a split bus
application?
Answer: Provide an isolated hot bus and an isolated neutral bus.
◉ What is the best fuse type to use for the DC feed to an inverter?
Answer: Class T.
◉ What type of DVOM should be used for low voltage
troubleshooting on an inverter that does not produce a true sine
wave output?
Answer: True RMS.
, ◉ What is the required cumulative CCA rating for a battery switch in
an inverter installation?
Answer: 801 or more.
◉ What tool is used to determine an inverter's level of EMI?
Answer: Gauss Meter.
◉ According to ABYC, how should the shore power grounded
conductor be handled?
Answer: It should not be grounded on board the boat.
◉ What is the first test if a customer complains about receiving
shocks from their boat when plugged into shore power?
Answer: Polarity check at the shore cord.
◉ What should be checked first if a customer complains of low
voltage at the AC panel?
Answer: Check voltage at the dock pedestal.
◉ What is a likely cause of a reverse polarity problem?
Answer: Improperly wired shore power cord, shore power inlet
receptacle, or reversal of hot and neutral conductors.
