A floating ground is a reference point for electrical potential in a circuit which is galvanically isolated from actual earth ground. Most electrical circuits have a ground which is electrically connected to the Earth, hence the name "ground". The ground is said to be floating when this connection does not exist. [1]
A distribution board, or circuit breaker panel, is typically a metal box mounted on a wall of the home. In many new homes, the location of the electrical switchboard is on the outside of the external wall of the garage. How services are connected will vary depending on the service provider and location of the home.
Even if all of the audio and video equipment in, for example, a home theatre system is plugged into the same power outlet, and thus all share the same ground, the coaxial cable entering the TV may be grounded by the cable company to a different point than that of the house's electrical ground creating a ground loop, and causing undesirable ...
Fire detection and fire suppression systems, such as carbon dioxide, may be installed. A large electrical room may have extensive provisions for grounding (earthing) and bonding enclosures of electrical equipment to prevent stray voltage and danger of electric shock, even during faults in the electrical system.
A distribution board (also known as panelboard, circuit breaker panel, breaker panel, electric panel, fuse box or DB box) is a component of an electricity supply system that divides an electrical power feed into subsidiary circuits while providing a protective fuse or circuit breaker for each circuit in a common enclosure.
Japan’s largest floating solar-power plant was damaged on September 9, after Typhoon Faxai made landfall in Tokyo and surrounding areas.A fire broke out at the plant, which floats on the ...
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 ...
"Floating fire ant colonies can look like ribbons, streamers, mats, rafts, or an actual 'ball' of ants floating on the water." Sadly, if you thought boats would be able to keep you safe from the ...
