Hi…

Welcome to electriciansjournal.com. My name is Jim Bernth, founder of Electrician’s Journal. I’ve been an Electrical Engineer for 36 years, and really enjoy writing condensed technical articles about topics that can benefit others in the Electrical industry. My goal is to summarize and condense potentially complex topics that are most important to Electricians as well as Electrical Engineers into a “take-away” format, and also share application-specific insight and experience. Every topic posted will likely be important to most people in the electrical industry at every level. Each post should take the average reader no more than 15 to 30 minutes to read. The number of topics posted are growing every day. If you have any questions or have interest in a particular topic and would like to see it posted, send all inquiries to: jimbernth@gmail.com.

Enjoy and visit often!

120VAC Wiring

120VAC Wiring

Introduction

In the United States, the standard nominal AC voltage for residential dwellings and some commercial is 120/240VAC, 60HZ. This voltage is derived from an outdoor transformer 240-volt secondary winding with a center-tapped neutral. The voltage on each side of the center-tapped neutral is 120Volts because 240VAC / 2 = 120VAC.

The common wiring devices inside a house are:

  1. 1-Pole Switches

  2. 3-way Switches

  3. 4-way Switches

  4. Dimmer Switches

  5. Receptacles

  6. Lighting Fixtures

  7. Smoke Detectors
