Can I connect multiple power supplies to a single outlet?

Question

I recently purchased two power supplies from Amazon: https://www.amazon.ca/gp/product/B07TWW8Q73/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&th=1 https://www.amazon.ca/gp/product/B005T6UJBU/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1

I currently have both of them wired to two separate outlets.

Is it possible to wire both of them to the same outlet? Maybe like this?

What would be the best way to split the wires safely?

The power supply on the left is a 24V 15A AC/DC power supply.

The smaller one on the right is 5V 3A AC/DC power supply.

Answer 1

Electrically, this will just work. Just wire them in parallel, like you have drawn. (I didn't check that you drew the wires going to the correct screws. I assume the drawing is correct.)

But safety-wise, I don't know the best way to make the parallel connection. If this was some little Arduino project I would just say to strip 3 wires, make a soldered connection and heatshrink it, but this is mains voltage so doing it properly does matter - you really need a strong connection that won't come undone accidentally, or you'll get a big spark and trip the breaker (best case) or electrocute yourself (worst case). If you are using fork terminals and two of them fit on one screw, then you might consider wiring the outlet to one power supply and then wiring that power supply to the other power supply, by putting the wires on the same screw, but don't quote me on that.

Answer 2

You can wire both power supplies to a household 120VAC outlet. However I recommend using separate power cables with each one terminated in a standard grounded plug. In this way the supplies will operate independently of each other and can be used at different locations if needed. This is the same as plugging 2 separate lamps into a dual outlet or separated outlets.
