Hi Steve - Great Electrical Repair Question! |
|
Make sure the power supply is fuse protected. Try to find a power supply that is rated for outdoor use. You should plug your power supply into a GFCI protected receptacle when in use outdoor. Understand that altering the original design of your unit will void the UL Listing and most likely the Warrantee.

Electrical TipThe Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical TesterThis 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. |
