Armored Cable bend through wall

I have purchased a home generator that came with 30' of armored cable. i ran the cable through my floor joists to the other side of my basement and down the far wall. i now need to make a 90deg bend to go through the outside wall. I know i can cut the conduit but the issue is that i can not pull the wires through the conduit, so how do i get connecter ends on this? Is my only option to cut the wires and wire nut them together inside of a box? I am just hesitant to cut the power wires and 5 smaller controller wires without be sure that there is not another/better way of doing this.

any other suggestions?

thanks

 

Lots of important details missing. Are you using a transfer panel or transfer switch or what. Never heard of a generator coming with a 30' length of AC attached to it so from what to where does this cable go.

 

That's 30' Ray

Still.....I haven't heard of that kind of a setup either and I install generators for a living.
Power wires and 5 controls wires in one cable ?

Usually since the control wires are low voltage they're run in a second conduit.

Do you have a link to this system ?
