The Westek Indoor Power Strip Timer is an easy to use 24 hour timer combined with an 8 outlet power strip. Four outlets are controlled by the timer and 4 are independent (always on), providing the ultimate in flexibility. You can program in 15 minute increments, up to 48 on and 48 off settings per day. Decorative cover hides and protects timer dial and settings. Non-removable pegs can’t be lost by user. Use it for a few indoor lights to keep you from coming home to a dark house or to give your home that lived-in appearance which will help deter criminals while you are away. By limiting the amount of time your lights are on, you can significantly reduce the amount of energy being used and eliminate the cost for that energy. It is a great low cost to automate your lighting up to 1875W (or 15 amps) and control the amount of power they are using. All outlets are 3-prong grounded. UL listed.
