Which component is used to bypass non-installed options during construction?

• A. Electrical Conduit
• B. Mast Installation
• C. Weight of Units
• D. Jumper Plugs

Answer: (D)

Jumpers plugs are used to bridge the option terminals so the system can run during construction even when certain features aren’t installed yet. They create a complete path in the control circuitry by linking the terminals that would connect to the optional component, preventing open-circuit faults and allowing testing and initial setup to proceed with the base configuration. This keeps the wiring consistent and avoids having to install every option just to test the core system. The other items aren’t meant for this purpose: conduit is for routing wires, mast installation is a structural step, and the weight of units concerns balance and support, not bypassing optional wiring.
