I reached out to the manufacturer, Buyers Products, who told me the Pre-Wired Switch Box with Relay and Circuit Breaker - Fused - Backlit - 6 Function # 3376391106 uses 16 gauge wire in switches 2 through 6 of this box.

I have added a link to a video review of this switch box as well as a link to the installation instructions for you to check out.

If the wires from switches 2 thru 6 are only 16 guage, then will they handle 20 amps???

Yes. The Buyers Products Pre-Wired Switch Box w/ Relay and Circuit Breaker - Fused - Backlit - 6 Function # 3376391106 will handle up to 20A. The 16 gauge wire will handle that capacity but the length of wire you attach to it can drop the amperage further so if you are looking for that power you won't want to go too far or you will want a different gauge wire attached for less drop. We normally recommend running 12 gauge from the battery to the rear of the vehicle for trailer power, so I'd run thicker wire for longer distances from the existing wires. The switches 2 through 6 are each directly switched and each protected by a 20A fuse on the back of the box so anything above 20A will pop that fuse.
