Low Voltage Lighting Transformer

[splinetto]

If I have 4 600w transformers,for 24v lighting, Can I put them all on the same 20a ckt. They both add up to 2400va or watts. Or do I have to figure on only uses 80% of the ckt?

We're you planning on maxing out the transformers? I myself would use a 14-3 branch circuit... if possible.

All the lights come on together so Im trying to see if i need a relay. And no I dont want to max out the transformers but be close to max.

Keep in mind that, in a perfect world where transformers are 100% efficient, VA in equals VA out.

A 3-wire circuit can work with a 2-pole switch or contactor.

You have 4-600w transformers. What's the connected load?
