Wiring Surveillance Flood Lights
Electrical Question: How should I provide power for Surveillance Camera Flood Lights?
My electrical wiring project involves Changing the Wiring of a Motion Detector Light on an Attached Garage of a Home.
- Hi Dave, I live in a 1977 ranch-style house where my porch is lit by two (original equipment) outdoor fixtures spaced about 20 feet apart, attached to the west side of the garage exterior?75 watts each. These of course can be turned on via a switch in the entry way hall. I also have two more outdoor lights installed on the front (north side) of the garage one on either side of the garage door to illuminate the driveway. These 2 fixtures were installed by me years ago and I just tagged on to the junction box of the porch light on the west side of the garage that was nearest to the front of the garage. So currently all 4 lights go on and off with the same indoor switch.
- My project is to replace the two fixtures on the front of the garage with 2 surveillance camera flood lights. Obviously these two flood lights will need power on constantly so I need to know the easiest way to rewire these 2 fixtures so they are no longer switched, but I want my 2 porch fixtures to remain controlled by the current indoor switch. My thought was to find the junction box closest to the garage (which will be in the attic), attach a new #12 wire there and run it to the two junction boxes that will house the new floodlights on the front of the garage. Of course I would disconnect the wire currently going to these fixtures from the switched junction box first. This would give constant power to the 2 front lights and the 2 porch lights would remain switched.
- The junction boxes in my attic are the square metal type (3- 4 inches square). How many #12 wires can I safely connect in this junction box? I have not been up there to look yet but obviously there is going to be at least 2 wires currently connected to each box up there. Would it be okay to add a third new #12 to power these floodlights? Thanks for any help/tips you can give!

Wiring to an Existing Power Source
The number of wires for a junction box depends on the exact box, however there are extension rings that can be added to most electrical boxes. For example you can get extensions for 4 Square, 3 Inch or 4 Inch Octagon boxes, as well as 1-gang, 2-gang and many other boxes.
Your power source may be from the existing light circuit inside of the garage, or from one of the wall receptacles. These options will depend on access, and if the walls and ceiling are covered are not.
Before making the connections, be sure you are not connecting to a wire controlled by a switch. This will require some testing or tracking down of the wiring to see where they end up.
Your plan is good, and you sound like a knowledgeable person, so I’ll bet you will do just fine.

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