Humidity control in waterproof box.

So I ended up shorting out an amplifier and a wifi receiver mounted in an outdoor box because I didnít know I should pack the incoming conduits with silicone and the heat from the electronics condensed enough water to short it out. Oops. So Iím replacing the hardware and will now seal the incoming conduits with silicone, but id like to add a dissecant just in case. Would silica gel work for this (I noticed thatís whatís packed in security camera domes) ? If so how much should I use. The box is 30x20x10cm and the electronics consume 85w.

You can't run electronics.... like a receiver... in a sealed box.

It is best to make ventilation holes at the bottom and cover with screen or sponge to keep bugs out.
avoid inserting wires on top to keep water out. Seal it with silicone if you don't have a choice.
Also, make drip loop on wire just before entering the box to keep large amount of water from hitting against penetration.
