Electrical Distribution and Protection
Equipment used to distribute power and protect other equipments and systems from current or voltage surges.

Battery Isolators - Battery Isolators divide dc current so that it only allows the current to flow in one direction for each battery. This enables charging of more than one battery from a one power source without connecting the batteries together.

Bus Plugs - Bus Plugs connect to a busbar or busways to distribute protect and supply power to industrial equipment.

Busbars and Busways - Busways and busbars (conductor bars)  provide current to distant or moving points along the path of an electrification system.

Circuit Breakers - Circuit breakers are mechanical switching devices capable of breaking currents under specified abnormal circuit conditions.

Electrical Insulators - Electrical insulators, high voltage bushings and porcelain insulator assemblies provide electrical isolation of power line conductors in transmission and distribution (T & D), substation, transformer, capacitor and power protection applications.

Electrical Terminations - Electrical terminations or terminators are electrical devices installed at the end of a bus or transmission line to prevent signals from reflecting back from the end, thus causing electrical interference.
 

Fault Detectors and Recorders - Fault detectors and fault recorders are electric power instruments that detect and/or record electrical faults that may happen in power lines. A fault recorder keeps a log about the time, location, intensity of the fault.

Fuse Holders - Fuse holders are devices for containing, protecting and mounting fuses. Blown fuses can be changed quickly and easily when used in conjunction with a fuse holder.

Fuses - Fuses protect electrical devices and components from overcurrents and short circuits that occur in improperly operating circuits.

Ground Enhancement Materials (GEM) - Ground enhancement materials (GEM) are conductive backfill materials used to increase the conductivity of the soil around grounding rods, bars or plates.

Ground Fault Relays - Ground fault relays protect electrical equipment from ground faults. A ground fault is an unintentional current path between a current-carrying conductor and a grounded surface.

Grounding Bars and Rods - Grounding bars and grounding rods are electrical connections that divert undesirable current in order to protect humans and equipment.

Grounding Grids - Grounding grids and mats consist of conductive mesh or sheets that act as a multipotential ground. They are used near pipelines, substations, transformers, large motors, or high voltage power lines to reduce mains hum, provide AC mitigation, and reduce step and touch potentials.

Grounding Indicators - Grounding indicators are used to monitor and verify the presence of grounding systems.

Grounding Straps - Grounding straps are anti-static devices that are used to protect people and electronic equipment from electrostatic discharges (ESD) by routing the electric current to a safe ground.

Lightning Protection Systems - Lighting protection systems provide reliable electrical connection to the earth or ground and can vary from simple copper rods to sophisticated electrolytic rod systems with active soil moisture replenishment.

Load Centers - Load centers are used for the protection and distribution of power in a building or residence. They are also called circuit breaker boxes.

Motor Control Center (MCC) Buckets - Motor Control Center (MCC) Buckets, are individual motor control modules intended to be installed in a motor control center, they typically contain a circuit breaker, a motor starter/contactor and may contain a transformer. Some more specialized mcc buckets may contain additional components for more advanced motor control.

Motor Control Centers (MCC) - Motor Control Centers (MCC) are a modular assembly which motor control units called buckets are installed, each bucket is intended to control a motor. It acts as a central switchgear panel for the control of multiple motors in an industrial facility.

Panelboards and Switchgear - Panelboards and switchgear are electrical distribution devices that convert incoming electrical power into several smaller circuits and provide overload protection in the form of fuses or circuit breakers.

Partial Discharge Monitors - Partial discharge monitors are used to monitor partial discharge activities in high voltage equipment.

Solar Junction Boxes - Solar Junction Boxes are used to house solar cables.

Thermal Cutoffs and Thermal Protectors - Thermal cutoffs and thermal protectors are nonresetting, thermally sensitive devices designed to protect domestic electrical appliances and industrial equipment from fire. They are sometimes described as thermal one-shot fuses.

Transfer Switches - Transfer switches transfer electrical power back and forth between two power systems or buses such as a utility power line and a backup motor-generator power supply.

Utility Meters - Utility meters are used to monitor the consumption of water, gas or electricity by businesses or residences.
