Connecting multiple AC transformers

[HelenaA]

Hi,

I am a newbie so be kind

I am trying to build a lighting rig using 6 x 12V/20W hallogen bulbs. I have 2 AC transformers each able to deliver up to 60W. Assuming both transformers are supplied by the same 240V AC input, is it ok to connect their outputs together in parallel to supply up to 120W? I understand their outputs would need to be in phase with each other.

Thank you so much
Helena

Make sure the transformers are not only the same rating, but the same manufacturer and model. In other words, identical. It is not good design practice to run 120 watts worth of lights on transformers who's total rating is 120 watts. Don't push it right to the edge.

Thank you for the advice! Much appreciated
