Description
The ECM INDUSTRIES LLC GTB-408 is an 8-circuit terminal block rated for 30 amps and 600 volts, designed for multi-conductor wire termination in electrical panels, control enclosures, and distribution systems. It accepts wire gauges from 22 AWG to 10 AWG, making it compatible with both signal-level and power-circuit wiring in a single block. The clam shell housing provides secure wire retention and straightforward access during installation or inspection. Electricians and control-panel builders use this block to organize multiple conductors in a clean, code-compliant layout without junction splices.
The GTB-408 is suited for residential and light commercial electrical work, including HVAC control panels, motor control centers, and low-voltage distribution enclosures. Its 8-circuit layout allows technicians to terminate multiple runs in one compact component, reducing panel clutter and simplifying future troubleshooting. The wide voltage rating of 600 volts covers most standard branch-circuit and control-circuit applications encountered in the field. This block ships in a package of 5 units, making it practical for jobs requiring multiple termination points.
Key Features
- 8 independent circuits in a single terminal block assembly
- Rated 30A and 600V for broad branch-circuit and control-circuit coverage
- Accepts 22 AWG to 10 AWG wire for mixed signal and power terminations
- Clam shell housing for secure conductor retention and easy access
- Sold in packages of 5 units per package quantity
Compatibility
Designed as an OEM-style replacement or new-installation terminal block for use in residential and commercial electrical control enclosures, HVAC panels, and distribution assemblies requiring multi-circuit wire termination.
Installation Notes
Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize all circuits and verify voltage is absent before terminating or removing conductors from the block. Use a calibrated torque screwdriver per the enclosure or panel manufacturer specifications when tightening terminal screws to avoid conductor damage. Confirm wire gauge and insulation rating are appropriate for the circuit load before making final connections.
