Developing Electrical Installation Details

Ankush Kumar
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.

    Hello Lee,


    Thank you for the reply. But as I mentioned , I got responsibility to develop Installation Details for Heavy Industries where the work process is different as compared to other sectors such as Infra, Railway etc. I am currently working with an EPC company where Installation details should include every minor detail to support the site construction team. These sites are located at remote locations where it is difficult to get the material from local market, if missed out . These Installation details should be developed that it should have low TIC (Total Installation Cost) as well.


    In first example you mentioned that you state

    " IP66 Junction, 20A Imin, 240VAC, X Kgs, manufactured to BS EN XXXX with minimum terminal capacity for X cables, to be mounted 1500mm from floor level with mechanical fixings to steel column. Junction box to be mechanically fixed to steel columns made of hot dipped galvanized unstrut fixings connected via stainless steel screws/bolts/nuts/washers. All cuts to be coated in a zinc rich cold galvanizing paint"


    I need to provide complete material details such as SS (316 or 304 or any other grade), bolt shall be cap head or machine screw or any other type ,bolt size 1/2" or 1/4 " or any other size, washer flat or round or square, lock washer requirement etc.

    Attached image is an example of motor Installation detail from reference project. The final Installation that I need to produce shall be similar what looks above.

    Hope you understand my concern now wink
