The Genie 76478GT is a genuine OEM Inline 4-Port Terminal Block designed for TZ-50 and TMZ-34/19 trailer-mounted articulating boom lifts. As a direct OEM replacement, this terminal block is manufactured to the same specification as the original component, ensuring correct fit and electrical continuity in the circuit it serves. Confirm part number 76478GT against your machine's parts manual to verify it is the correct item for your unit before ordering.
Key Features
- Genuine OEM Electrical Conformity — Manufactured to OEM specification, ensuring correct terminal sizing, contact rating, and insulation grade for the circuit this block serves.
- 4-Port Inline Configuration — The four-port inline design allows multiple conductors to be joined or distributed at a single connection point, matching the original wiring layout without rerouting.
- Direct OEM Replacement — Drops in as a like-for-like replacement for the original terminal block on the TZ-50 and TMZ-34/19, preserving the integrity of the machine's electrical connections.
- Verified Fitment for Trailer-Mounted Booms — Confirmed for Genie TZ-50 and TMZ-34/19 trailer-mounted articulating boom lifts, so you can order with confidence.
- Electrical Reliability — A sound terminal block maintains secure, low-resistance connections between conductors. A loose, corroded, or failed block can cause intermittent faults, control failures, or complete circuit loss.
- Operational Safety — Electrical connection integrity is critical on aerial boom lifts. Replacing a damaged terminal block with a genuine OEM part helps ensure the machine's electrical circuits perform as designed.
A terminal block is an electrical connection component that joins two or more conductors at a secure, insulated termination point. In an inline configuration, it allows wiring runs to be connected, extended, or distributed without splicing bare wire. On trailer-mounted articulating boom lifts like the TZ-50 and TMZ-34/19, maintaining clean and secure electrical connections throughout the machine is essential for reliable control system operation. A worn, cracked, or corroded terminal block can introduce resistance into the circuit, cause intermittent electrical faults, or interrupt functions entirely — making timely replacement with the correct OEM part the straightforward fix.
