Best way is to determine how many lights you want. You can fit a lot lights on a 300 Watt transformer which is a 2.5 AMP. A 600 Watt transformer has a 5A. But that doesn't mean you'll use all those AMPs. Often you will only use about half. Hope this helped!
Thank you so much, Adam! Your videos are awesome, and you have helped me out tremendously with my landscaping project in my backyard
Helpful. Thanks. On the other end of the 12-2 wire, how do you know which one was on the 13 V and which one was on the 12 V?
Measure it with a multi meter
How do I determine how many transformers I can pick on a single 120V 20amp house circuit? Thank you.
