Frequently Asked Questions (FAQs)

1. Can timers be used outdoors?

Any outdoor lighting, including seasonal lighting, could use a timer. They are available as analog or digital timers that can be hard wired or simply plugged into the nearest outlet. Their capabilities range from scheduling multiple events across the week to extremely accurate astronomic timing using photocells.

2. Can you use a timer with a GFCI outlet?

No, the GFCI won't appreciate having its power interrupted. Go the other way: put the GFCI in front of the timer, so the timer is after the GFCI. Alternately, if the bathroom receptacle circuit powers only receptacles in this bathroom, you can tap the "LOAD" side of that GFCI and feed it to the timer.
