i have been searching the internet to see if here in california is is a code requirement( nec,cec, ubc, etc.) to have housekeeping pads for transformers and switchgear. if you know of the article number please list it thanks
I couldn't tell you specifically for CA, but all other National codes do not require housekeeping pads. It is a design issue. Sometimes they are needed for stuctural reasons to support the concentrated weight of heavy equip.
