Be sure that your saw can handle a dado blade. Many of those direct drive saws can’t.
If you don’t have a manual, you might be able to find one online.
If you can’t find out for sure about the saw’s capacity, at least be sure the arbor is long enough that the saw stack can fit with the arbor washers and the nut and still have some threads left sticking out past the nut. This is very important.

The 8” size dado is OK, but if you saw is a little under powered, you can even use a 6” dado. Since a dado is not normally a through cut, they don’t have to be as large as the 10” blade. A 6” blade can still cut over an inch deep dado and that’s more than enough, usually, and takes less horsepower to run.

I know some of the benchtop saws, like the Porter Cable for instance, only allow 6” dado blades and only 1/2” wide.

I must confess, I have an 8” dado set and my saw is designed to handle it, but I find that it’s more trouble to change out the blades, change out the insert, than to just make several passes with the regular blade. Some day, if I get a second saw, I may keep one set up with a dado, but till then I just make multiple passes with the regular blade. That could change depending on what I’m working on of course.
