I'm building an oven. I've already got the skin on and bricks in. I haven't cut the grooves for the elements yet mostly because I'm trying to figure out what gauge and how long and how I am going to arange them. The chamber of my oven is 9in wide 6.5in tall and 22 in deep. I've gone through the tutorial about how to make them but I'm still kind lost. Here are my questions

Is 4000w on 240v enough?
I think I should be using 14awg kanthal a1. Right or should I be using 15 or 16?
I'm guessing I will arange the elements in the oven based on the length?
I can post some pics later if that will help
