A disconnecting means 'in sight from the motor' is intended and used only as an emergency disconnecting means.

• A. True
• B. False
• C. Only for motors under 1 hp
• D. Only for indoor installation

Answer: (B)

Having a disconnecting means that is in sight from the motor is about safety and clear isolation. It ensures there is a visible, readily accessible point to de-energize the motor circuit so maintenance and servicing can be done safely, with the operator able to confirm the switch is open before touching the equipment. This setup is not intended only for emergencies; it serves as the normal means to disconnect power for routine servicing and to satisfy safety requirements. The idea that it’s used only for emergencies is incorrect because the in-sight disconnect is provided so maintenance personnel can securely lock out and work on the motor knowing the circuit is truly isolated. The other notes about only applying to motors under a certain horsepower or only indoors aren’t correct either, since the requirement is about visibility and accessibility for safe shutdown, not restricted to a specific size or indoor installations.
