What is a key requirement for the disconnecting means in typical residential installations?

• A. It must be readily accessible.
• B. It must be located next to the main service disconnect only.
• C. It must be inside the equipment enclosure.
• D. It must be remotely controlled.

Answer: (A)

The essential idea here is safety through quick, manual control. In typical residential setups, the disconnecting means must be readily accessible so anyone can shut off power quickly in an emergency or for maintenance without barriers, tools, or special access. “Readily accessible” means you can reach and operate the device without climbing, entering locked rooms, or moving heavy objects.

That’s why this option is the best: it ensures immediate and straightforward disconnection when needed. The other ideas don’t fit because a disconnect doesn’t have to be restricted to being right next to the main disconnect, it doesn’t have to be inside the equipment enclosure, and it shouldn’t rely on remote control for normal operation, all of which could hinder safe, rapid isolation of power.
