A relay contactor is a large relay, usually used to switch current to an electric motor or other high-power load.
Large electric motors can be protected from overcurrent damage through the use of overload heaters and overload contacts.

If the series-connected heaters get too hot from excessive current, the normally-closed overload contact will open, de-energizing the contactor sending power to the motor.

How Electrical On-Delay Staging Relays Work

This section will cover the use of relays that are sometimes needed to control special device loads such as Air Conditioners and other high demand equipment from starting at the same time.

Electrical Relay Construction and Purpose - Part 1

This section will cover how relays are constructed and operate due to the current flowing through the control coil and the mechanical reaction that takes place.

Electrical Relay Construction and Purpose - Part 2

This section will cover the use of electrical relays contactors and how they are wired and function in a motor control application.

Electrical Relay Construction and Purpose - Part 3

This section covers time-delay relays and how they can be constructed to delay armature motion on coil energization, de-energization, or both.

Electrical Relay Construction and Purpose - Part 4

This section explains how protective relays are used to monitor the current, voltage, frequency and more in the electrical power industry.

Electrical Relay Construction and Purpose - Part 5

This section will discusses the limitations of solid state relays due to contacts, size and operation speed.

Electrical Tips to Help You Wire it Right

The Safest Way to Test Electrical Devices and Identify Electric Wires!

The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester that I use to easily Detect Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.

The Quickest Way to Check for Faulty Electrical Wiring!

The Plug-In Outlet Tester
This is the first tool I grab to troubleshoot a problem with outlet circuit wiring. This popular tester is also used by most inspectors to test for power and check the polarity of circuit wiring.
It detects probable improper wiring conditions in standard 110-125 VAC outlets Provides 6 probable wiring conditions that are quick and easy to read for ultimate efficiency Lights indicate if wiring is correct and indicator light chart is included Tests standard 3-wire outlets UL Listed Light indicates if wiring is incorrect Very handy and easy to use.

Strip Off Wire Insulation without Nicking and Damaging the Electric Wire!

The Wire Stripper and Wire Cutter
My absolute favorite wire stripping tool that I have had in my personal electrical tool pouch for years, and this is the tool I use to safely strip electrical wires.
This handy tool has multiple uses:
The wire gauges are shown on the side of the tool so you know which slot to use for stripping insulation.
The end of the tool can be used to grip and bend wire which is handy for attaching wire onto the screw terminals of switches and outlets..

The wire stripper will work on both solid and stranded wire. This tool is Very Handy and Easy to Use.
