Hi!
Need some advice

I have 2 20A switches in my kitchen which are unused:


When I first renovated years ago, I couldn't decide if I wanted to get a microwave and oven fitted into my kitchen cabinet, so I left those cabinet empty, and my contractor just terminated the wires for me.

Top:



Bottom:



Questions that I have:
1. What is the difference between the top configurations and the bottom configurations?

2. I want to buy a microwave with oven combo: Something like this specs: Panasonic Microwave Oven
These microwave ovens normally come with a normal 3-pin plug. Can I remove the plug and connect the microwave wires directly to the 20A switch wires via the terminal connectors?

Thank you in advance for replying!
