What size should the fixing bolts for the distribution box be
When the distribution box is installed on the wall, it should be fixed with split bolt (expansion bolt). The bolt length is generally the sum of the embedded depth (75-150 mm), the thickness of the box bottom plate, the thickness of the nut and washer, plus the "head allowance" of about 5mm. Check for proper IP/NEMA ratings and material quality. The fixing method should be firm and reliable to avoid movement or tilting of the box due to vibration or. 4 KV Substation of the ratings indicated above. The body of the boxes shall have sufficient re- enforcement with suitable size of channels keeping a provision for fixin andle conforming to general. The most common size screw to use in an electric box is a 6-32 flathead screw. For heavier applications, like ceiling lighting and ceiling fans, an 8-32 screw will work better.

How to connect the grounding wire of the optical cable in a mobile optical distribution box
Run a minimum 14 AWG copper grounding wire (or as specified by local code) from the bonding clamp to the nearest grounding electrode or equipment grounding bus. Keep this conductor as short and direct as possible — avoid sharp bends that increase impedance. Follow these steps at each cable entry point and termination location to achieve a compliant, safe ground bond: Identify metallic components. Strip back approximately 6–8 inches of the outer jacket using a cable slitter or ringing tool. Visually identify armor, strength members, or foil layers. The grounding point should be selected in a stable, dry, non-corrosive. An optical ground wire (also known as an OPGW or, in the IEEE standard, an optical fiber composite overhead ground wire) is a type of cable that is used in overhead power lines.
