may i join in this one ??
ok i did look at the NEC 96 edition. old art. 384-15
" Number of overcurrent devices on one panelboard"
Not more than 42 overcurrent devices [other than those provided for in the mains] of a lighting and appliance branch-circuit panelboard shall be installed in any one cabient or cut out box.
A lightingand appliance branch-circuit shall be provided with physical means to prevent the installation of more over current devices than that number for which the panelboard was designged, rated, and approved.
so in my option here most imporat part that should read the breaker box label for listing for the numbers and types of breakers that approved for that usage
if i am off track let me know then i can correct my mistake here.
p.s. i did look at my french electrical codes and they say the same thing too.
Pas de problme,il marche n'est-ce pas?"(No problem, it works doesn't it?)
