What is the spade lug size needed for this power supply? Or can I insert Pomona banana jacks into the terminals?

You will need a size of at least 6mm for the spade lug or a diameter of 4mm for banana jacks. Hope you find this helpful.

could this power a 500w 4-channel amplifier for car speakers? it has a 60amp fuse and only requires 12v to turn on.

short answer is no. 13.8 is standard automotive voltage at maximum charge, so that will be fine. but this PS will not deliver the 60 amps. most likely the self-protection circuit in the PS will "fold back", that is deliberately throttle the current delivered to a low value. this normally entails a concurrent reduction in output voltage and that will cause your amp to turn-off. turning the PS power switch momentarily off should clear the fault. while both amp and PS may survive the event, it is a warning that either could fail the next time around.

Can this supply be used to power a 5 amp dc motor?

I'm afraid that the SPS-1330 is not designed for powering DC motors. We recommend you choose an adjustable DC power supply instead, such as our SPS-3005 series.

Is this a switching supply ??????

Yes, this is a switching power supply.
