What is advised regarding electrical supply on apparatus?

• A. Never operate multiple electrical devices at once
• B. Avoid overtaxing the electrical supply
• C. Always run on maximum load
• D. Disconnect all lights when not in use

Answer: (B)

Electrical supply on apparatus has a finite capacity, so avoid overtaxing it. Running too many high-draw devices at once can cause voltage drops, tripped breakers, blown fuses, and overheating, which can interrupt critical gear like pumps and radios when they’re needed most. Manage loads by keeping nonessential devices off or on separate circuits, and if you must use heavier equipment, stagger its use or connect to an appropriate power source rather than pushing the system to its limit. It’s sensible to turn off lights or equipment that aren’t needed to save power, but don’t eliminate all lighting—safety lighting and essential indicators should stay active. The other options imply extremes—never using multiple devices, always operating at maximum load, or disconnecting all lights—which aren’t practical or safe.
