    Can I possibly connect directly the 12v to the other 12v from my 12v-0-12v transformer? So that I can have 24v? Is that safe?

    You can ignore the 0v C.T. and go from each end to give you 24v.

    Welcome to AAC!

    The transformer is already wired that way. Just don't use the center tap.

    Ahhh, okay. So I connect one 12v to the circuit and the other 12v to the circuit also? And ignoring the 0v. That gives me 24v right?

    I thought connecting the 2 12v to the circuit and 0v to the circuit also, will give me 24v. Thanks! Much appreciated!

    What you referred to as a 12-0-12 transformer is also referred to as a 24VCT transformer.

    From Wikipedia

    Observe the centre tap on the secondary (Right), do Not connect to it when requiring 24vac.
    Use the outer two.
