Hi folks - I'm posting this message in the 'Lighting' and 'Landscaping' forum with the hopes of clarifying something I don't have too much experience with. I'm in the process of constructing this 2-post pergola on the side of my house. I'm incorporating 4' tall cedar planter boxes at the base of each post, which allow me to grow climbing plants in. I currently have a 'VOLT' low-voltage transformer plugged into a GFCI to the left of pergola (as depicted by that black arrow). I have two low-voltage lighting fixtures that currently feed into that transformer to light the front side of house. I eventually want to add two additional low-voltage fixtures to provide uplighting to the two pergola post. I drew white Xs to represent the locations of those two additional spotlights. The problem I'm facing is that there's only 1 available clamp connector inside my transformer. I assumed that I could only plug in a single fixture into each clamp connector. I read somewhere that I could actually plug in multiple wires into a single clamp connector. It sounds dangerous, so I just wanted to post the message to get feedback from people that understanding lighting better than myself. Thank you kindly!
