Hydrogen outgassing, electrical consumption and the myriad code requirements much venting over the need for ventilation

There appears a level of consternation swirling about of late that is rooted in varying interpretations by Authorities Having Jurisdiction (AHJ) such as building inspectors, electrical inspectors and so on regarding international building codes now that they have been adopted over national codes in many US jurisdictions. The intention of this paper is to identify the international codes covering hydrogen evolution in stationary battery strings and compare them with national codes, IEEE practices, Telephone company best practices and practical experience. Conclusions to be drawn will identify perhaps a need for soundly reasoned input to the next international code cycle and a reiteration of best practices for stationary battery installations.
