Top of The Morning Charlie, thank you for the daily read and your daily work in educating us further your input is always appreciated. When installing or replacing the screws for a load center cover, if the screws become stripped out in older existing installations when doing service work or have been lost, is it a code violation to install a sheet metal screw or a thread forming screw to get the cover installed? The instructions that I have read (SQ D QO) say to install the cover with the screws provided. Most load centers and covers are entirely painted surfaces but it appears the screws that come with the cover might have some bonding capabilities that a substituted screw might not have. 110.3(B) requires following manufacturer's instructions, 250.4(B)(4) would require bonding of the cover. 250.8(A)(5)&(6) mention the screw thread requirements, 250.12 discusses clean surfaces.
