Leviton Telcom 460MF5WLEV 60A Mechanical Interlock

Product Description

The LEVITON TELCOM 460MF5WLEV is a 60-amp mechanical interlock designed to prevent two circuit positions from being energized simultaneously. Mechanical interlocks are a critical safety component in electrical panels and transfer switch applications, ensuring that two breakers or disconnects cannot both be in the ON position at the same time. This type of device is commonly installed by licensed electricians during generator hookup projects, standby power installations, and service panel upgrades where a physical lockout mechanism is required by code.

The 460MF5WLEV is suited for use in residential and light commercial electrical installations. It is typically applied in scenarios where a generator feed and a utility feed share adjacent breaker positions, and a hard interlock is required to satisfy National Electrical Code requirements for transfer equipment. The unit is sold individually and is appropriate for installations requiring a 60-amp-rated mechanical interlock solution.

Key Features

• 60-amp rating suitable for generator transfer and dual-feed interlock applications
• Mechanical design physically prevents simultaneous engagement of two adjacent breakers or disconnects
• Sold as a single unit for targeted replacement or new installation
• Hardware accessory category item designed for panel and transfer equipment use

Compatibility

Designed as an OEM-style mechanical interlock accessory for 60-amp-rated breaker or disconnect configurations. Verify panel or disconnect model compatibility before installation, as mechanical interlock fitment is position- and enclosure-specific.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements for transfer equipment and interlock devices. Always shut off and lock out the main utility feed before servicing any panel or disconnect enclosure. Do not force the interlock mechanism into position; confirm breaker spacing and slot alignment match the interlock design before securing. Inspect for proper operation of the interlock action before restoring power.
