Plug And Socket

Although a plug and socket may seem like a small part of the electrical system on a project, they play a critical role in how safely temporary power is supplied to tools, maintenance equipment, and mobile equipment at the job site. We provide industrial plug and socket systems after evaluating the current rating, number of poles required, and the working environment where they will be used. The requirements for a single-phase service power (e.g., in a utility room) would be very different to those for a three-phase heavy-duty receptacle installed near process machinery. Ingress protection, mechanical strength, and locking arrangement are all factors that determine the potential for accidental disconnection under load.

Pin configurations of the plug or socket (i.e., pin position and configuration) must match the voltage and frequency of the supply system to prevent incorrect connections from occurring during shift changes. Body materials of plugs and sockets must be selected based on whether they will be exposed to oil vapours or be used outdoors, and they should be easy to clean if they are regularly washed down. Practically sized entry and gland spaces will also ensure that terminations are secure, even after repeated use. Location and mounting positions in distribution and power control panels will be such that access to them from outside will not disturb adjacent feeders or cause a safety hazard to persons working at the project.

All plugs and sockets are inspected for contact grip, insulation resistance, continuity before being shipped out. If they are used in US facilities, they offer a safe and rapid power connection for portable equipment while reducing loose wiring on the shop floor, and providing a constant connection to power sources where there is a potential for vibration.
