Maxi 40 Amp Fuse Panel

[mtrawls]

Our team did not receive the Maxi 40 Amp Fuse panel in our KOP -- we mistakenly got 2 of the low amp fuse panels. We contacted FIRST, but haven't yet received a response, and, as it is somewhat important to move forward, have purchased one elsewhere. (It is brass and very heavy .) Anyway, each fuse accept a different input power source, and we have to, therefore, split the power coming from the 6 AWG wire from the fuse breaker into 4 to power it. I just wanted to make sure all this is legal, i.e., using a different fuse panel than that provided in the kit (granted that none was provided in ours). I didn't see anything immediately applicable from a glance at the electronics/wiring section. Thank you.
