The importance of bonding and grounding in commercial, industrial, and institutional buildings cannot be overstated. The grounded circuits of machines need to have an effective return path from the ...

Tim Oldershaw and Dave Stefanowicz look at earthing in data systems in buildings and point out where things can go wrong. Many datacomms contractors often do a good job installing the racks, cables ...

IN 1941 the Council of the Institution of Electrical Engineers set up a special committee to consider the problems arising from the increasing use of multiple earthing of the neutral conductor in ...

Cressall has demonstrated its design and manufacturing capacbilities by producing specialist neutral earthing resistors (NERs) suitable for use in explosive atmospheres. The NERs meet the ...

The change lifts a ban on inserting a switch, circuit or fuse into mains power earthing systems in houses and businesses.

A core-balance protection device serves as an example of how these switches operate. Phase and neutral power conductors pass through a toroidal (differential) current transformer. Under normal ...
