To add to this, the breakaway cable should also be shorter than the chains, thus if the trailer ever leaves the ball, the breakaway will activate the brakes BEFORE the chains fail, a long cable is counterintuitive and will only activate if the ball disconnects and both chains fail. Be careful with the coil type cables as they appear to be connected correctly when in reality they may be too long.
