Can I Install a 120 Volt Hour Counter with a 220 Volt Circuit?
No – you cannot connect this hour counter up as you have described, here are your options to make it work…
Electrical Question from Kathy about 220 Volt Wiring Diagram – Hour Counter
Background: Kathy, a Homeowner from Oceanside, CA
Question: I have a 220VAC system that I need to add an hour counter to. It is a 2 wire system with both lines having 110VAC, together 220VAC. The hour meter says that it is rated 75 to 270VAC. It says to hook up the AC hot to Pin 1 and the AC neutral to pin 2. I just hook up 1 line to each pin right?
Thanks for your electrical question Kathy. No – you cannot connect this hour counter up as you have described because the 220 volt circuit of the vacuum does not have a neutral. So you either need to obtain a 220 volt hour counter or install a separate 120 volt power source to the vacuum unit for the hour counter and install a 220 volt relay which would be used to control the voltage to the hour counter.

The Safest Way to Test Electrical Devices and Identify Electric Wiring!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, [amazon.com], I use for the detection of Standard 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.
