Happy Friday.
There's a reason you never see a pre-made 110V or 240V electrical connection with two different plug connectors and only one socket connector. They're simply a bad idea. Just like a cable with a plug connector at each end. Bad. Very, very bad.
As I am an electrical engineer, do you need me to explain it to you, or are you willing to just take my word for it? Or are you unwilling to accept that this is a bad idea unless you prove it to yourself somehow?
