    摘要: A method of determining a prospective short circuit current for an electrical system including a source includes connecting a test load between either: (i) a first phase line and a second phase line of the electrical system or (ii) the first phase line and the neutral line of the electrical system, employing a sensor coupled to the electrical system to measure a voltage drop across the test load, determining a voltage value based on at least the measured voltage drop across the test load, determining a total effective impedance for the first phase line to the source, and determining the prospective short circuit current based on the voltage value and the total effective impedance.

    摘要: A coupling includes a male adapter and a female adapter, and may include a nut and a sleeve. In embodiments, the male adapter includes a male adapter inner diameter, and may include threads. The female adapter includes a female adapter outer diameter. The nut or other formation may be configured to engage at least a portion of the male adapter. In embodiments, one or more contact points may be provided between the female diameter outer diameter and the male adapter inner diameter, and the female adapter outer diameter or the male adapter inner diameter may be configured to be out-of-round. The male adapter may include a shoulder and the sleeve may cover the shoulder in connected configuration. Methods for forming a coupling are also disclosed.
