Distribution Box and Selection Guide: Internal Structure, Components
Learn how to choose a distribution box and understand its internal structure, including MCBs, busbars, neutral bars, earth bars, RCDs, RCBOs, SPDs, enclosure ratings, and wiring layout.
Safe Clearances for Electrical Equipment: Working Space and
Side clearance: There should be a minimum of 30 inches of clearance from the sides of all electrical equipment, but in no case less than the width of the equipment itself. This is referred to
Minimum And Maximum Spacing Of Beam, Column, Stirrups, Slab
In general, the spacing between two bars in a beam depends on the maximum aggregate size used in the concrete. The minimum spacing between the two bars can be about 50–75 mm.
Chapter 2. Design of Beams – Flexure and Shear
There is one very important difference. For a column, the axial load causing buckling remains constant along the length. But, for a beam, usually the lateral-torsional buckling causing bending moment M(x)
