Talk:Inrush current
From Wikipedia, the free encyclopedia
Dear tech,
Base on my knowledge, the breaker sizing should refer to the total amp and multiply by the surge factor (1.6). Our client refuses to install the SPD(surge protection device), but they want to maintain the sizing base on the total load without the surge factor calculation. They request an advice from us. Which method of installation is correct and how do I prove it to them? For additional information, the incoming source will be from UPS. As I know, surge current might occur during the switching of the breaker. If we don’t take the surge factor into consideration, it might trip the breaker. How the surge occur during the breaker switching and what causing it?
Please assist me on this. Hope to get your prompt reply since we are in the middle of acceptance test.
