Selecting the wrong size conductor in an electrical installation can have dangerous and disastrous results with conductors too small for the applied load.
An electrical plans examiner’s duties include reviewing specifications, drawings, and engineered plans to verify compliance with local, state, and national standards.
Supply-side connected PV systems require renewed attention due to the more detailed requirements added to the 2020 NEC.
Chances are you will have to perform some sort of calculation in order to apply the requirements of the NEC and provide that installation that safeguards people and property from the hazards that arise from the use of electricity.
In this follow-up article, we will try to answer some common questions, take a closer look at how the manufacturers of steel conduit and tubing address corrosion, and offer additional specific potential solutions to ward off the effects of corrosion
Now that we have a series of equations relating to power, voltage, current, and resistance, I want to crank through some simple example calculations.
Absence of voltage testing is a vital step in the process of verifying and establishing a de-energized state of any electrical system.
Lightning’s perfect storm for destruction is on the solar field. Solar panels’ large—and often exposed and isolated—location make surge protection critical for it to last its lifespan.
What type of copper conductors and copper-clad aluminum connectors are Certified (Listed) for terminating copper-clad aluminum conductors?
What is the rating of a branch circuit, feeder, or consumer’s service as mandated by the Canadian Electrical Code?
