Colour-coded terminal blocks avoid bad termination

BLOCKMASTER Jelly Beans JB6 Series of modular thermoplastic terminal blocks come in multiple colours for ease in identifying terminations and preventing costly field wiring mistakes. Products can eliminate the issue of installers terminating the wrong wire to the wrong terminal. For example, line input 120/220 connections can be made to a white block, while low voltage connections can be made to a green terminal block. If more than one type of low voltage control is necessary, other colors can be used. Firm offers screen printing to mark alphanumeric characters on product series to further simplify field wiring. Devices are modular in construction, allowing users to obtain the exact length needed.
