I asked the question of Dewalt about the reset breaker on the 733 and have not received a reply. The question is CAN the new style breaker for the Type 2 machine be used in an old type 1. I need the part and would rather go with the updated version if possible. I can see no electrical reason or space reason that it would not work. It is the same machine with just a few mid product model changes. (shipping is more than the part). Thought about just plugging it into a GFCI or AFCI and leaving the part off. I've completely torn the machine down and rebuilt it otherwise and it works fine with the breaker bypassed. (briefly of course)
