Selecting the wrong size conductor in an electrical installation can have dangerous and disastrous results with conductors too small for the applied load.

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.

When people ask me, “What is electricity?” I tell them that electricity is the presence of voltage.

This short article discusses the purpose of system grounding, grounding requirements, separately derived systems, and available short-circuit current. Hopefully, it will clear up any misunderstandings or confusion surrounding the grounding and bonding of vehicle-mounted (trailer) mobile generators.

It is getting closer to the holidays, and many individuals will be tasked with installing holiday lighting and other electrically operated devices outside their dwelling units. Many folks find it a challenge to find accessible outdoor receptacle outlets for this purpose.

Join Keith Lofland as he explains how to calculate the minimum number of lighting circuits for residential dwelling units (general purpose).

With options of panelboards, switchboards, and switchgear, the electrical system designer has a robust palette of options to provide the required overcurrent protection for conductors throughout the facility.

NFPA 70E Article 120, Establishing an Electrically Safe Work Condition, provides the lockout and tagout requirements necessary to provide an electrically safe work environment for the employee.
