I was always taught when doing an upfit you only replace 1 for 1, meaning if here was 1 existing head on an arm-over you couldn't say add another "new" head and now be feeding 2 heads off that same arm-over, otherwise you'd have to add a new arm-over to the branchline for the new head. Now that may have come from a spec long long ago but I swore it was also in NFPA, however I don't see it worded that way in the standard. Any help?
