For single family homes, the business disconnect way shall have a rating of less than 100 amperes, 3-wire. A larger company may be compelled for brand-new homes or additions to currently homes based on the actual fill calculations. (CEC 230.79(C))Service entrance Conductors (Wires) – Conductors that extend across a roof shall have a minimum vertical clearance the 3’ over the roof surface for roofs sloped 4:12 or more (18” clearance required when conductors enter through the roof overhang/eave). The business head candlestick be located so that the business drops, in addition to the open up wires between the business head and also service drop, will have a minimum clearance that 10’ vertically above ground and also 3’ radius native doors and also windows. (Article 230.24)The neutral (grounded) conductor need to be figured out with white tape in ~ both terminals. (Article 200.6(B)(4))Service entrance conductors and cables chandelier be approved for a wet place and, as soon as exposed to straight sunlight, chandelier be provided and significant as “sunlight resistant.” service entrance conductors and also conduit candlestick be sized according come the complying with table (based on CEC chapter 9 table 1):
