Another version is the Posi-Lok, which features keyed, shrouded connectors, and panels with sequencing interlocks. [3] Camlock is generally used where temporary connections of 3-phase and/or more than 50 A are needed. Applications include connecting large temporary generators or load banks to distribution panels or building disconnects. Common ...
In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.
Hubbell had been one of the first to manufacture flush toggle switches for alternating current only. The first Safety Receptacle was designed and produced as were the original "grounding only" devices which helped to set the standards for the industry. And while Hubbell was busy on land, the company found new opportunities at sea.
NEMA wall receptacles can be found installed in any orientation. Neither NEMA nor the US National Electrical Code nor the Canadian Electrical Code specify a preferred orientation, but the National Electrical Contractors Association's National Electrical Installation Standards (NECA 130-2010) specify that the preferred location of the ground is ...
High-voltage switchgear A section of a large switchgear panel. Tram switchgear This circuit breaker uses both SF 6 and air as insulation.. In an electric power system, a switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment.
IEC 60309 (formerly IEC 309 and CEE 17, also published by CENELEC as EN 60309) is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes".
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
The EDP is designed for use in an emergency, when the MODU or WIV needs to quickly disconnect, and move away from the oil/gas well that it is drilling or working-over. [1] Examples of when this might be necessary include unexpected extreme weather that exceeds the MODU/Vessel's capability to maintain its position.
