What's the most practical way to merge multiple AC Devices into one single cable?

I thought aboit it, and what if I solder multiple screw terminals on a PCB, fix them tight, attach a 50A AC fuse for safety, and solder and wire everything together with proper thickness cables? I think 6 AWG should be enough for the load that I plan to apply to it, around 50 amperes in total.

Will that work? Will the PCB burn at 50 amperes of load? There will be both AC and DC parts on that PCB.

More details on hardware:

Project requirements:

• One DC power supply for all DC components
• One AC aquarium water bubbler
• A Raspberry Pi 4
• Some buck converters
• Steppers (biggest current eaters)
• Sensors

AC Parts:

• 12V power supply - its load will consume most of the electricity
• 220 AC squarium air pump maximum 5W of power consumption, more likely 3W.

Schematic (I'm new to Kicad and electronics in general so it may have some issues):

IMPORTANT NOTE: ONLY the bottom 3-screw terminal is connected to the mains. The rest of connectors represent: "hot" of the water air pump/ DC power supply, "neutral" of the water air pump/ DC power supply, and grounding in the case of the PS

Note:

• The AC sign was the only symbol I could find for "hot"
• The "X" symbol means NOT connected. I'm used to the spiral size on schematics so I wanted to point that out
