Industrial Control Transformers – commonly used to step-down voltages where machinery or equipment controls need lower and accurately regulated voltages.
Drop-down Cable – flexible, durable, water-proof wire that is commonly used for drop lighting (pendant lighting) and in industrial or commercial settings where overhead cranes, hoists or equipment is manually operated by a hanging pendant switch. Drop-down cable is often used when equipment operators need to stay at a safe operating distance from a machine but still require the ability to remotely activate the emergency stop, pause or start controls of machinery.
Hook-up Wire – stranded or solid wire that is commonly used to wire circuits inside electrical panels and equipment control boxes. The colors of hook-up wire include: red, orange, yellow, green w/yellow stripe, blue, purple, white, gray, black, brown.
Stretchable Wire – stranded and shielded wire used where wires are subject to flexing and stretching.
Machine Tool Wire – coolant and oil resistant, designed for electrical wiring of machine tools.
Building Cable – wire or sets of wire with a slick plastic outside sheath commonly used to wire buildings. The plastic sheath allows the wire to be easily pulled through wall studs and floor or ceiling joists. NM-B building cable/wire is suitable for dry locations. UF-B building cable/wire is suitable for wet locations and outdoor or underground feeders.
Armored Building Cable – for convenient installation in dry locations.
Outlet Boxes and Covers – a variety of outlet boxes and covers are available for all applications. Some of these are designed for wet locations and shield outlets from splashing and debris. Others have been designed for wall, pole or floor mounting. There are also options for surface mounting and recessed mounting.
Enclosures – many applications require that electrical components are protected by enclosures. There are a variety of enclosures that are designed to shield electrical components from impacts, water, oils, chemicals, corrosion and other hazards. Some enclosures are available in easy access and see through designs. Others are hardened cases with securely fastened covers. There are also enclosures that are submersible or designed for underground use.
Raceways – electrical raceways are used to route, protect and/or shield wires and cables. Some raceways are only intended for organizing and neatly routing wires and cables. Others can serve multiple purposes including routing hose and cable. Conduit raceways have several applications and care must be taken to choose the correct conduit and conduit fittings for each specific application. There are also numerous cable carrier designs that allow flexing for moving or vibrating machinery. Cable carriers also are intended for use with hoses.
Sleeving – electrical sleeving is used to protect wires and cables from a number of hazards. Some of these hazards are: chemicals, flames, heat, abrasion or sparks. There is tube sleeving and wrap-around sleeving. Wrap-around sleeving can be used without disconnecting the ends of wires and cables where tube sleeving must be slid over the wire or cable from an end.
Plugs and Receptacles – choosing plugs and receptacles depends on the type of equipment or machinery that needs to be powered and other location or environmental hazards that are present. There are designs that protect the plug/receptacle connection from impact, water, oil, chemicals, heat and vibration. There are several application specific prong configurations available which include locking style blades and straight blades. Locking style (turn-lock) blades prevent unintentional disconnections due to movement, vibration or impact.
Circuit Breakers, GFCI and Circuit Breaker Boxes – circuit breaker boxes house and distribute electricity to various circuits in a building or structure. Circuit breakers prevent circuit overload and different circuit breakers have different ampacity ratings. The ampacity rating of a circuit breaker is chosen to protect a circuit from overload. Corresponding conductors for higher ampacity circuits must be of a adequate wire gauge to safely distribute electricity to the load on the circuit. Note, the total calculated load on a circuit, specific application, conditions and environment along with the adopted NEC® standards (of your locality) ultimately determine the design of a circuit, circuit breaker ampacity and type. NEC® (National Electric Code) provides guidance for the safe installation of wiring and equipment. When a locality or municipality adopts NEC® standards they become regulation (law) and must be followed.
Grounding Rods/Equipment – conductive surfaces, equipment, machinery, enclosures and structures should be sufficiently earth grounded to protect people from dangerous electrical shock. The goal of earth grounding is to provide a return path for electricity in the event that there is a short circuit or failure of equipment that causes it to become dangerously charged with electricity. By the nature of how electric current flows, it tends to choose the path of least resistance. At no time is it ever safe for a person to become the path of least resistance. By correctly grounding equipment, the risk of dangerous electrical shock can be minimized. Note, a qualified electrician should be employed to ensure the integrity and adequacy of grounding conductors and equipment.
