What if I want my power supply conform to UL authentication?

ul authenticate

It's a quasi switcher power supply, transformerless, using a N-channel MOSFET to turn on and off and regulate the Mains voltage to 24VDC. I need to make this board conform to UL authentication. What shall I do when comes to component selection and PCB layout. thanks in advance.

It's a quick question....but with very very long answer........

First you need to determinate where the power supply will be used for ?
Consumers electronics ? IT equipments ? others ? After you know that....Purchase the UL standard associated with this particular area......

Please tell me where you think the power supply will be used , what area ?
