Which statement is true about power connections when using a capstan hoist?

• A. The capstan hoist should be the only item connected to the power source.
• B. Other tools may be connected to the same power source as the capstan.
• C. The power source should be switched off at all times.
• D. A separate generator should be used for the capstan hoist.

Answer: (A)

Capstan hoists demand a dedicated power supply because their motor can draw a high startup current. Having the hoist on its own circuit prevents overloading shared outlets, avoids voltage drops and nuisance breaker trips, and keeps control systems stable so the hoist starts and runs reliably. Sharing a power source with other tools can cause disturbances or faults in one device to affect the hoist, which is unsafe and inefficient. Keeping the power source dedicated also makes isolation for maintenance easier and reduces the risk of backfeeding. Leaving the power off all the time would make the hoist unusable when needed, and using a separate generator isn’t usually necessary if a proper dedicated supply is available, though it can be used in field conditions. The essential idea is to isolate the capstan’s power to ensure safe, predictable operation.
