    Have you ask for this?
    No I did not. What's your approach when estimating switchboards and determining how many sections will need to be attached?

    I was more referring to:

    What is a great way to ask questions that you need a little help with?

    My answer is that I ask questions here.

    Exactly what the OP is doing.....

    There is no magic wand for this one. What I do is twofold:

    Mostly I look at the floor plan and whatever the EE draws I take off, figure a single section is 36 wide (they could be 42 and a pull section could be 24) And I measure the footprint. The other thing is I rely on experience. As I and others have said before, it is an estimate. If they expected it to be perfect, they would call it an exactimate. I've had 40 hours in an estimate and needed more like 80 to put the gear together and vice versa. With gear that size, you will lose it or make it up somewhere else.


    I know what I don't know, and I know where to go to find it!
