Hello all. I have a two part question:
1. We are doing some work on a multi unit light industrial warehouse. This particular building has 6 units fed from a Siemens I-T-E switchboard. Each unit's distribution panel is fed from a Siemens TFP223 fusible pullout. I was told by someone, that if anything in the unit we are working on is under load that removing the pullout may cause an arc. Even in light industrial applications I have never really seen these types of mains used and don't have experience with them so although that doesn't seem accurate I can't say for certain.
2. Why are fusible pullouts used as opposed to standard breakers? Pullouts seem less convenient, I'm wondering what the pros/cons of the different mains are.
Thanks in advance.
