Description
Product Overview
The Leviton LITLK Manual Transfer Interlock Kit is engineered to give homeowners, electricians, and facility managers a dependable method for safely toggling between utility power and an auxiliary power source such as a generator. Constructed from high‑impact, flame‑retardant polymer, the interlock is designed for surface‑mount installation on standard 15 A circuit breakers. The kit includes a single white‑finished interlock device that snaps securely into place, providing a physical barrier that prevents simultaneous connection of utility and backup power. This eliminates the hazardous condition known as back‑feeding, which can endanger utility workers and damage equipment. The product dimensions (11.18″ D × 13.07″ W × 11.18″ H) and a lightweight profile (0.4 oz) make it easy to handle and store. Leviton backs the kit with a 10‑year limited warranty, underscoring confidence in durability and performance.

Usage
Designed specifically for Leviton load center panels, the interlock is ideal for residential homes, small businesses, and light‑industrial settings where a reliable backup power solution is required. When a power outage occurs, the user simply turns the utility breaker to the OFF position, installs the interlock, and then engages the generator breaker. This sequence guarantees that only one power source is active at any given time, protecting both the electrical system and personnel. The kit is also suitable for seasonal use, such as during winter storms or summer heat waves, where temporary power loss is common. Because the interlock is a manual device, no additional electronics or batteries are needed, simplifying maintenance and reducing long‑term costs. Its white finish blends seamlessly with most panel interiors, preserving the aesthetic of the electrical enclosure.

FAQ
Can the interlock be used with non‑Leviton panels?
While the LITLK is optimized for Leviton load centers, it can be installed on other panels that accept standard 15 A breakers, provided there is sufficient clearance for the device.
Do I need any tools to install the interlock?
No special tools are required. A standard screwdriver is sufficient to secure the interlock to the panel, and the device snaps into place without additional hardware.
Is the interlock compatible with all generator sizes?
The interlock works with any generator that can be connected to a 15 A breaker. For larger generators, a higher‑rated breaker and a compatible interlock model would be needed.
What maintenance is required?
Periodic visual inspection for dust or corrosion is recommended. The interlock does not contain moving parts, so routine cleaning with a dry cloth is typically all that is needed.
How does the warranty work?
Leviton’s 10‑year limited warranty covers defects in materials and workmanship. If a failure occurs within the warranty period, Leviton will repair or replace the unit at no charge.
