Customer Questions & Answers

I want to use this as a dedicated timer for outlets for outdoor decor like x-mas lights. Is this possible?

I want to use this as a dedicated timer for 4 or 5, 15 or 20 amp outdoor outlets for outdoor decor like x-mas lights. All outlets in turn would be on a dedicated breaker. Is this possible? Is this safe? Is there a cheaper or better way to get all my lights to come on and turn off at the exact same time on a residential level?
Asked by: Matt
This is an INDOOR timer. If you want the time clock outside to control lights, you will need the outdoor model. Figure your total load watts/volts=amps, ex. 4800 watts divided by 120 volts = 40 amps, which is the maximum rating for this timer. This will require a 40A single pole circuit breaker into your main electrical panel (or into a sub panel) with 3 #8 wires (one black and one white [neutral] to power the clock, and one black (or blue or red BUT NOT WHITE OR GREEN to supply power to the load (your outdoor outlets). Then use a copper lug connector to connect your 4-5 outlets #12 wire to the #8 load wire. Tape well with cloth electrical tape covered with plastic electrical tape. FOR OUTDOOR SAFETY, use GFCI ground fault receptacles in an outdoor box w/cover. OR you can wire directly w/o use of plugs (receptacles). GOOD LUCK

The timer part of my intermatic t-100 timer stopped working..I can manually turn it on/off with the lever...is this repairable or do I need to replace

I checked the timer dogs and they were on tight...
Asked by: Wayne
I have been using one hardwired in-line for thirty years and have had to replace the mechanism twice for your symptoms. Unfortunately the mechanism is not available without the box. I could not figure out what was wrong in either case.
