Installing Electrical Boxes In Plaster Walls

By Dave Rongey - Summary:

How to Install Electrical Boxes For a Smooth Finish: The result will be a smooth finished look of the wall and the electrical devices.

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.

Dave’s Reply:
Thanks for your electrical wiring question Brian.
