Spur circuits attached to the ring can overheat if not fused at the spur-point (i.e., if a BS 5733 or similar fused spur is not used) This is almost certainly a breach of the appropriate electrical standards (e.g. BS 7671 in the UK): the maximum load on any unfused spur is a single fitting.
Digital model railway control systems are an alternative to control a layout and simplify the wiring and add more flexibility in operations. A number of control systems are available to operate locomotives on model railways. Analog systems where the speed and the direction of a train is controlled by adjusting the voltage on the track are still ...
When running a regular (non-wireless) circuit, the electrician must drill a hole through all of the logs to get each wire to the switch location. The electrician also must cut a large hole in the log to install a switch box. Wireless switches do not need switch boxes because there are no wires and no routing is needed.
A branch off of a final circuit supplying a single accessory, especially from a ring final circuit. Fused spur A spur branched off of a final circuit via a connection protected by a suitable fuse, and thus one that may connect to more than one accessory. A de-energized circuit A circuit that is isolated from power and not at a potential ...
In electronics and electrical engineering, a fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its essential component is a metal wire or strip that melts when too much current flows through it, thereby stopping or interrupting the current.
The fuse element, or "fuse link", is the replaceable portion of the assembly that melts and breaks the circuit when the electric current through it exceeds its rated current value. There are many types of fuse elements for many different uses such as a type T fuse also known as a "slow-blow fuse" being used for sidelines.
In the IEEE 802.11 wireless LAN protocols (such as Wi-Fi), a MAC frame is constructed of common fields (which are present in all types of frames) and specific fields (present in certain cases, depending on the type and subtype specified in the first octet of the frame).
An antifuse is an electrical device that performs the opposite function to a fuse.Whereas a fuse starts with a low resistance and is designed to permanently break or open an electrically conductive path (typically when the current through the path exceeds a specified limit), an antifuse starts with a high resistance—an open circuit—and programming it converts it into a permanent ...
