Positioning Electrical Back Boxes For a Smooth Finish
Electrical Question: When fitting an MK3704 Mounting frame do I have to sink the back Box further into the wall rather than flush to the plaster? I ask because, when screwed to the box, the mounting frame seems to sit proud of the back box and as such the plastic switch cover does not look as if it would sit flush to the wall.
This electrical question came from: Brian, a Handyman from London England.
Thanks for your electrical wiring question Brian.

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.
