Hi Folks
I am about to start building my first panel that is of a fair size. Therefore I would like to ask for advice on certain things before make mistake. I got myself familiar with posts with tricks & tips on panel building, however still would like to get few bits clarified. They're as follows:
Your comments are much appreciated, at the moment I am a little bit limited with choice of enclosures I can use so have to work with what I have access to. I have done some cad layouts following best practice but they do not necessary work well for me and need lot of tweaking. Particularly the distances between devices confuse me. I do not want clutter and also would like to ensure good air flow for cooling and no interference.
Thanks
Pat
I am about to start building my first panel that is of a fair size. Therefore I would like to ask for advice on certain things before make mistake. I got myself familiar with posts with tricks & tips on panel building, however still would like to get few bits clarified. They're as follows:
- What distance would you normally leave between top of device/component and wire duct?
- I do understand that it is recommended to keep the switching/power part in separate enclosure than control part, how critical this is though? If I have small pumps, few boilers and other bits and pieces without VSD etc. to worry about, do I really need that separation or would it be acceptable to throw everything in large non-separated enclosure? I have larger 'control' part that I would need large enclosure for and then I would left with half empty switching part (relays, contactors, MCBs etc) to match the size of control one, hence the desire in one large enclosure with everything in.
- How do you attach components such as duct to the door? Is it glued?
- What wire numbering systems do you use? I am aware there is no standard for it and every organisation using own internal methodology, could you suggest something to start with in order to let me develop own methodology based on?
- How do you estimate cooling requirement for panel (i.e. fan or vent slots).
