no, as long as the wire is made for outdoors. how many amp breaker are you using? I think you mite have a hard time with #6 wire, it is very stiff and there's not much room to bend it around in the box. it's a 30 amp box, you don't need #6 wire

A good inlet for a power generator
The power inlet was easy to assemble. I used # 10 wire to connect up to a double pull 30 amp breaker. It's better to use thinner wire such as #12 to make it easier to make all the connections. This box can adequately hold a connecting 30 amp 10/4 power cord in place. A better method would be to use a twist lock adapter to ensure the power cord stays well connected to inlet box.

Great Product
Bought this to complete my home generator setup. Mounted easily to outside wall to run cable to breaker panel in basement. Quality construction. A little pricey but it's hard to fine a NEMA male twist-lock plug and box for DIY'rs. Best value was Home Depot. Worth the price to do the job the right way. Purchased online from Home Depot, fast delivery. Very satisfied with product and service.

This is the one you want. (assuming you have the same 30A connector of course). Don't bother with some of the "cheaper" brands that offer this similar product. This one is straight forward and nice quality. It is easy to install and has a nice weather proof cap system. Heavy duty and should last a good long time. Hey, these days YOU NEED a generator! This item makes it smoother and much safer/proper to hook up during those times of uncertain grid flow..
