Meltric Industrial Plugs & Receptacles

More Information about Meltric Plugs and Receptacles

Meltric Switch-Rated Plugs and Receptacles

Meltric switch-rated plugs and receptacles can be used to safely make and break electrical connections under load. This is an important feature in industrial settings where equipment may need to be disconnected for maintenance or repair while still under power.

Meltric High-Ampacity Plugs and Receptacles

Meltric high-ampacity plugs and receptacles handle high amperage loads without overheating or suffering from contact degradation. This is achieved through the use of spring-loaded silver-nickel contacts, which provide a low-resistance connection that can handle high amperage loads with ease.

Meltric Multipin Plugs and Receptacles

Meltric multipin plugs and receptacles are designed for use in industrial settings where there is a need for a high number of electrical connections. These connectors are commonly used in applications such as machine tools, robotics, and other automated equipment where multiple signals or power sources are required.

Meltric Hazardous Location Plugs and Receptacles

Meltric hazardous location plugs and receptacles are designed to provide safe and reliable electrical connections in hazardous environments. They are engineered to prevent sparks and excessive heat, are durable and resistant to harsh environmental conditions, and can be quickly and safely disconnected in case of an emergency.

FAQs 

What is branch circuit disconnect switching?

A branch circuit disconnect switch is a device that is used to interrupt or disconnect the flow of electricity in a specific branch circuit. One of the primary purposes of a branch circuit disconnect switch is to provide a means of safe maintenance and repair.

What is a switch-rated plug used for?

A switch-rated plug is designed to provide a safe and reliable connection between a device and a power source. It has special contacts that are rated for switching duty, meaning that they are capable of withstanding the arcing and heat generated when the electrical load is switched on and off.

Grounding Requirements

The National Electrical Code (NEC) states that electrical systems must be grounded to a point that the maximum voltage, to ground underground conductors, does not exceed 150 volts. It also states that any 3-phase 4-wire, Y configurations and Delta configurations have the neutral wire grounded as well. These requirements cover any electrical systems ranging from single-phase 120 volts, all the way to 3-phase 480 volts AC. The conductor that needs to be grounded in these types of systems will always be the neutral wire. 

Bonding Conductor

A bonding conductor is needed between the grounded conductor and the equipment, grounding the conductor to the metallic enclosure of the main electrical service. It is important to make sure that a properly sized conductor is used to accommodate the potential surges that may occur in the electrical system. When grounding in a separately derived AC system, which is a system where components such as a generator can have the grounded conductors, where continuity is possibly interrupted by a transfer switch, it is important to make sure that the grounding conductor is bonded to the equipment grounding conductor of the metallic chassis on the load side of the electrical service through the use of a main bonding jumper. When continuity is not being interrupted on the load side, then it is critical to make sure that there is no bond between the neutral wire or grounding conductor and the metallic chassis of the electrical service. This will allow the main bonding to occur at the main service panel entrance point.
