I am currently involved in the development of Electrical Installation Details for heavy industries (Oil & Gas/Power/Metal & Mining) in my current organization. I need guidance from community SME/engineers/designers to develop these Installation details that will finally be issued to construction. I will share my concern with some examples below:
Example 1
If I need to develop an Installation detail for Junction box or convenience receptacle mounted on steel column using unistrut P1000 or angle, what are all hardware's should be selected.(type of nut, bolt, size, washer etc.) ?
Example 2
For Junction box or convenience receptacle mounted on concrete column what should be the size of anchors bolt selected ?
Example 3
For Installation detail Cap head bolt or machine head screw which one fits best ?
Example 4
Does the nut size selected is suitable as per hole size ?
As there are many vendors and technically one or other is acceptable, how to make decision to choose best one for the project ?
Look forward for your experience and guidance on the subject.
