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

Circuit tracers or signal tracers are used to troubleshoot circuits. They are relatively simple electrical testing instruments that enable electricians and other users to locate, trace and identify common electrical problems such as breakers, shorts

Switch boots protect switches from contaminants such as dirt, dust, gas, and liquids.  They are generally tough, pliable silicone rubber devices for toggle, pushbutton, rocker and rotary switches.

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

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

Electrical contact and electrode materials are soft, high conductivity, oxidation resistant materials used in circuit breakers, relays, and for EDM applications

Plugin style surge suppressors plug into wall outlets to protect equipment from transient overvoltages.

Terminal and junction boxes are used to house electrical components and facilitate wiring. They are T-shaped or rectangular, made from a variety of materials, and available in many different sizes, sealing configurations and mounting styles.

Metal oxide varistors (MOV) are semiconductors that protect electronic components and systems from transient voltages.

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.

Dataline and DC signal surge suppressors protect equipment from transient overvoltages present on data or DC signal lines.

Transient voltage surge suppressors protect against temporary excess voltage and/or current in an electrical circuit that has been disturbed.

Power connectors transfer AC or DC through a variety of electronic devices and are used in a variety of commercial, industrial, and residential applications. Power connectors range from simple AC or DC inlets and outlets to sophisticated power entry modules

Power distribution units (PDUs) have an electrical input and several outputs, often as electrical outlets, for powering multiple devices. 

Power strips are used in applications where multiple AC outlets are needed, often without surge or line noise protection.
