Floors-2-Go, Newport, 2009 Floors-2-Go, Cardiff, 2009 Floors-2-Go, Basingstoke, 2008. Floors-2-Go was founded in 1999 as a family business, with the first store opening in Birmingham. In 2004, the firm floated on the London Stock Exchange. This saw the firm evolving from cash-and-carry (wholesale)-type warehouses to retail superstores. [2]
[1] [2] The use of concrete enclosed grounding conductors was added to the U.S. National Electrical Code (NEC) in 1968. It was not required to be used if a water pipe or other grounding electrode was present. In 1978, the NEC allowed 1/2 inch rebar to be used as a grounding electrode [NEC 250.52(A)(3)].
IG does not break ground loops, which can damage equipment like computers, printers, etc.. Interconnected computer equipment often benefits from single-point grounding. IG is only used with special equipment that requires it. The IG is typically insulated and separate all the way back to the point of earth grounding rod outside of the building.
While the national wiring regulations for buildings of many countries follow the IEC 60364 terminology, in North America (United States and Canada), the term "equipment grounding conductor" refers to equipment grounds and ground wires on branch circuits, and "grounding electrode conductor" is used for conductors bonding an earth/ground rod ...
A concrete spacer with a plastic clip in use Concrete spacers in a precast element Diaphragm wall block on rebar for a Diaphragm wall. A rebar spacer is a short, rod-like device used to secure reinforcing steel bars, or rebar, within cast assemblies for reinforced concrete structures. The rebar spacers are fixed before the concrete is poured ...
The electrodes for electrical grounding are often called ground rods and are often made from steel with a copper clad surface – typically 1 to 2 m long and 20 millimetres (0.79 in) in diameter. These are driven vertically into the ground and bonded together with bare copper wire. [1]
Grouted tiebacks can be constructed as steel rods drilled through a concrete wall out into the soil or bedrock on the other side. Grout is then pumped under pressure into the tieback anchor holes to increase soil resistance and thereby prevent tiebacks from pulling out, reducing the risk for wall destabilization.
An antistatic floor mat or ground mat is one of a number of antistatic devices designed to help eliminate static electricity. It does this by having a controlled low resistance: a metal mat would keep parts grounded but would short out exposed parts; an insulating mat would provide no ground reference and so would not provide grounding.
