Notice: Installing additional electrical wiring should be done according to local and national electrical codes with a permit and be inspected.

How to Keep Electrical Wiring Safe for Future Use

The process of disconnecting and safe keeping of unused electrical wires to be available for future use.

• Identify the old furnace circuit at the electrical panel.
• Turn the circuit breaker into the OFF position.
• At the old furnace location, the circuit wiring should be completely disconnected and removed from the old furnace.
• Install the circuit cable into a junction box where each insulated wire is capped off using wire nuts or insulated wire connectors, then place a blank cover over the junction box.
• A surface mounted junction box is typically installed for this procedure when the box is sized appropriately for the size of the circuit wires.
• The exact type of junction box will depend on the location and available access to the circuit cable.
• The junction box should have a clamp or fastener for the cable, and the cable should be secured using a cable strap or staple where the cable is exposed before entering the junction box.
• The circuit breaker should now be relabeled as the old furnace circuit and that it is unused or spare.

IMPORTANT:
Electrical panels have exposed wiring and components that are energized with electricity. It is not recommended that homeowners perform work in electrical panels but rather contact a qualified electrician who has experience working in home electrical panels.
