installed a sub board the other week for battery heating systems. i took my distrubtion from the main board in that floor. this in turn was fed from a big old fashioned swtch cabinate in the basement. The problem was that when i came to wite the cert i got a little confused on how to write the supply characteristics and earthing arangements, particular arrangments at the origon. because there are two boards before u get to the origon i was edgy on what to write. Would be gratefull if anyone else whom has more expierence writting niceic sheets than i do. THANKS!.
