Adapting 10/3 to new transformer?...... 2 of our 5 low voltage transformers, used for low voltage landscape lighting, have died and needed replacement. In my rush to get them replaced, I ordered a couple nice Volt Brand 12v low voltage transformers with astronomical timers and when they arrived today, I realized I had a problem with the current wiring. The dead transformers that are being replaced use a 10/3 12v setup that I am not familiar with and am not sure will work with the new transformers. Since our lighting setup is pretty comprehensive, I am REALLY hoping I can avoid doing new cable runs. I have attached a picture of the terminals of the transformers being replaced. I have also attached the PDF manual for the product. In short, they are 600w 12v ac transformers but instead of the standard 2 wire terminals, it uses a 10/3 setup. I assumed one terminal was common but it looks like I am wrong.

I cannot even find 10/3 transformers for 12v ac on the web, so I am a bit confused why our electrician used these only 4 years ago when we had everything installed. Is there any way to make this work? Thank you SO much in advance!

I am rewiring old fixtures for LED and have to swap out shunted to non-shunted tombstones. My old tombstones are wired with a solid aluminum wire. I have 2 bulbs in each fixture and since they are wired on one side, I wanted to daisy chain the 2 non-shunted tombstones in parallel and then splice it to the inbound 110V coming into the fixture. The new Leviton 13180-U tombstones call for 18AWG - but everything I read says that 18AWG is used primarily for 24v/48v applications and that's really my worry. Can I safely use 18AWG wire to run 110v into and between the tombstones? Thanks.
