Limit switches on gravity davits should be tested by __________.

Question 1 of 27070

Limit switches on gravity davits should be tested by __________.

🔍 Key Concepts

• Gravity davits operation and purpose of limit switches • Manufacturer’s recommended method for testing electrical safety devices • Why some methods could be unsafe while the winch is in operation

💭 Think About

• Which option actually checks that the limit switch works under real operating conditions, instead of just cutting power elsewhere? • If the winch is running, what is the safest way to see whether the limit switch will stop it at the end of travel? • Do all the listed methods truly test the switch itself, or do some just stop the winch without involving the switch?

✅ Before You Answer

• Identify which choice specifically involves the physical actuation of the switch mechanism while power is applied. • Eliminate any options that would bypass the limit switch instead of testing it. • Ask whether engineers in the engine room normally have direct control of davit limit switch testing procedures.

Question 1 of 27070

Limit switches on gravity davits should be tested by __________.

the engineers, from a panel in the engine room

shutting off the current to the winch

pushing the switch lever arm while the winch is running

all of the above
