The relay box by GSE can control 8 lamps with 600W or 2 lamps with 16A. The first 2 power cables stand for 2 circuits and they connect with electrical sockets. The relay box has 2 own electrical sockets, too. You connect your lamps with these sockets. You should know that you can only use 4 x 600W lamps on one socket (Total 8 x 600W). On the third cable you attach the timer.
If you connect your timer with an electrical socket to control several lamps, the timer will fuse. You can avoid that, if you use a relay box.
