Working with Telephone System Wiring

Application: Wiring a Telephone.
Skill Level: Beginner to Intermediate. This electrical wiring project is best performed by a Licensed Electrical Contractor or Certified Electrician.
Tools Required: Basic Straight Slot and Philips Screw Drivers, wire strippers for 20 to 24 gauge wire.
Estimated Time: Depends on personal level experience and ability to work with tools and small phone wires.
Precaution: If installing or relocating additional telephone wiring the main phone cable or the Test Jack should be disconnected before working with the wiring.
Notice: Installing additional telephone cable and wiring should be done using approved phone cable and phone jacks that are approved and compatible with the local telephone system specifications.

Identifying and Rewiring Telephone System Equipment

Many business telephone systems use proprietary telephone equipment. Typically the telephone service from the local telephone company comes into a main box from the local CO or Central Office. From there the phone service is connected to the in-house phone system, starting with a main system terminal box. Many of these phone systems are proprietary and require using only their specific telephones which may be connected to the system. The telephone system typically have special functions that are compatible with the system.

When a Telephone System is Not Working
If the telephone system is not functioning properly then there may be a problem with the telephone system, and not the telephone, so replacing telephones may not solve the problem, in fact replacing a proprietary telephone with a non-compatible telephone may damage the equipment or not work at all.

Troubleshoot The Telephone System Problem
If the telephones are not working right then this is an indication that the system has a problem and the system equipment and wiring should be looked at to see where the problem really is, and it may be something really simple, such as a wiring problem in the office area where telephone cables may have been damaged.

Replacing a Business Telephone System
If a business telephone system needs to be replaced then all of the proprietary equipment must be removed and replaced with the new system in order to maintain system compatibility. The telephone system cables and wiring assignments will need to be identified and reassigned as needed for the application. Consult the telephone system documentation for complete instructions.

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.
