In the very-dangerous instance of a reverse polarity bootleg ground, the hot and neutral wires have been connected to the opposite terminals, and a jumper or pigtail connection is made between the green bonding screw terminal and what is believed to be the neutral circuit.
The flat parallel plug blades are polarized to prevent the hot and the neutral connections from being reversed. In addition, many versions have a molded obstruction bump on top of the adapter, to block the grounding prong and thus physically prevent forcible insertion of a 3-prong plug in the wrong orientation.
Detectable errors include reversed hot/neutral, missing electrical ground or neutral, and others. However, leakage current through surge protective metal-oxide varistors connected between neutral and ground of a power strip can give a false indication that a ground connection exists.
A pole will be either a neutral [12] connection or a line [13] Neutral is usually very near to earth potential, usually being earthed either at the distribution board or at the substation. Line (also known as phase or hot, and commonly, but technically incorrectly, as live) carries the full supply voltage relative to the neutral (and to earth).
WASHINGTON (AP) — Forget about red hot. A new color-coded heat warning system relies on magenta to alert Americans to the most dangerous conditions they may see this summer.
Hot flashes and night sweats may harm the brain, heart and more, according to new research presented at The Menopause Society conference. Hot flashes are more dangerous than previously thought, so ...
Leg as in "hot leg" refers to one of multiple hot conductors in an electrical system. The most common residential and small commercial service in Canada and the U.S., single split-phase, 240 V, features a neutral and two hot legs, 240 V to each other, and 120 V each to the neutral. The most common three-phase system will have three hot legs ...
