How Electrical On-Delay Staging Relays Work
By Dave Rongey
Summary: 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.
Problem Solvers for Air Conditioners - Energy Savers for Large Electrical Loads
This method will help prevent nuisance tripping of sub-feed circuit breakers and reduce the electrical demand on your utility service which could lead to much higher energy bills.
ICM100/101 DELAY ON MAKE.
• 3 or 5 minute fixed.
• Works with anticipator thermostats.
MODE OF OPERATION:
When power is applied to the input, the time delays begins. After the time delay is complete, the load energizes and remains energized as long as power is applied. The control is reset by removing power during or after the time delay period.
1. Disconnect power.
2. Connect terminals in series with the
starting device as shown in the wiring
3. Reapply power, check operation.
4. Trickle current bypass resistor
T1 to T3 <1K ohm.
2-Wire Compressor Staging/Startup Delay Timer:
• Voltage: 18-30 VAC
• Frequency: 50/60 Hz
• Output Ratings:
– Maximum: 1.5 amps
– Minimum: 40 mA
– Inrush: 15 amps
• 3 or 5 minute fixed
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.
