If the outlet box is recessed, remove wall board until the bracket contacts the box to ensure a secure attachment.
Is it necessary to turn off the wall switch before wiring?
Simply turning off the wall switch is not sufficient. To avoid electrical shock, ensure that the electricity is turned off at the main fuse box before wiring.
What wiring connections should be made using wire connectors supplied?
Make sure all wiring connections are tight, including the ground, and that no bare wire is visible at the wire connectors, except for the ground wire.
