Early generator interlock kits consisted of two sliding steel or plastic (depending on the brand) plates held together by three bolts and installed on the front cover of the home's breaker panel, however, some models made by Eaton (formerly Cutler-Hammer) and Siemens for panels manufactured by them install on the adjacent circuit breakers themselves and consist of a sliding arm for breakers ...
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.
A switchgear may be a simple open-air isolator switch or it may be insulated by some other substance. An effective although more costly form of switchgear is the gas-insulated switchgear (GIS), where the conductors and contacts are insulated by pressurized sulfur hexafluoride gas (SF 6). Other common types are oil or vacuum insulated switchgear.
Instabus, is a decentralized open system to manage and control electrical devices within a facility.It is developed by Berker, Gira, Jung, Merten and Siemens AG.There are about 200 companies of electrical supplies using this communication protocol.
A Siemens air circuit breaker rated for 1000 V and 2500 A continuous current mounted on a motor control cubicle. Medium-voltage circuit breakers rated between 1 and 72 kV may be assembled into metal-enclosed switchgear line-ups for indoor use or may be individual components installed outdoors in a substation.
Simplified single line diagram of a single-phase transfer switch to select either 'city' (utility) power or local generator power 3-phase Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a ...

The network isolator is a passive device, and functions without any requirement of an external power supply. A functional equivalent to network isolators is Ethernet over a small stretch of optical fibre, using media converters or Ethernet switches/network cards with fiber connections on each end.
