National Power Equipment is your source for used and remanufactured air and vacuum circuit breakers, protective relays, current and potential transformers, trip devices, fuses, substation switchgear, and related parts.
The following are normally required: (i) Each circuit-breaker, disconnector and earthing switch mechanism box shall carry a label giving the NGC operational reference (to be specified by NGC) of the device. (ii) For GIS equipment each partition between gas zones shall carry labels giving the ...

We now know that our homes are contaminated with high frequency voltage transients. The ground wires in our homes actually are bonded to the neutral wires in our circuit breaker boxes. This means that the high frequency voltage transients that are created and released into the neutral w...
In the course of his highly classified contract work for the NSA, the US intelligence agency, Snowden uncovered unconstitutional surveillance programs that trace and store the electronic pathways etched across the Internet by hundreds of millions of Americans. NSA surveillance also sweeps up and archive...
After examining the pump, cleaning the cannon plug pins, and reconnecting the cannon plug, a mechanic was able to reset the circuit breaker without any further difficulty. During the flight from Atlanta to Miami, the public address (PA) system stopped functioning. According to passengers on that...
When the first switching means ceases to conduct, energy stored in the inductance of a power source connected to the circuit breaker is partly dissipated in the resistive means and partly transferred to the capacitor means, and while current in the resistive means is interrupted by the second com...
Confusion: make complex the relationship between the plaintext and ciphertext. A simple substitution cipher would provide very little confusion to a code breaker. The challenge is to create a set of FREQ and RREQ messages that hash into codes with a high degree of Diffusion and Confusion. One...
