Most everyone knows that electrical panels must be kept clear at all times and last year I wrote an article explaining the "why's" of this clearance requirement. Well now, NFPA is driving home the importance of these clearance requirements with a REVISION to the NEC, Sections 110.26(A) and 110.32. These PROPOSED revisions would more clearly define the space that MUST remain clear by requiring additional markings (e.g. the ever so popular sign like the one shown to the left will become obsolete). This new requirement would entail additionally marking the HEIGHT, WIDTH, and DEPTH (already required) of the working space for all equipment covered by the requirements of Sections 110.26(A) and 110.32 (e.g. 600 Volts, Nominal, or Less and Over 600 Volts, Nominal). Here is more from Jeffrey Sargent, a regional electrical code specialist for NFPA.
