Mr. Castello

It is the purpose of this writing to follow up our phone conversations of 1/22/09 and 1/23/09 regarding those areas encompassed by the 2009 code definition of Wind Borne Debris Region. The definition reads; “Areas within hurricane prone regions defined as that area east of the inland waterway from the NC/SC state line north to Beaufort Inlet and from that point to include the barrier islands to the NC/VA state line.”

The definition is intended to address two coastal groups independently as follows:

1. From the NC/SC state line north to Beaufort Inlet – The wind borne debris region is that area east of the inland waterway (intracoastal waterway)

2. From Beaufort Inlet north to the NV/VA state line – The wind borne debris region is the barrier islands


I hope this information helps.

Use of SEC Aluminum Wire in Dwelling (also applies to SEC Copper Conductors)

Hi Bill,
I don’t think I answered this question yet, I apologize.

If Table 310.15(B)(6) applies to a main power feeder, there is no temperature limitation mentioned in that Table. There must not be but one feeder that supplies the entire load of the dwelling in order to use that Table. Note that 4/0 AL conductor, with an allowable ampacity per Table 310.15(B)(6) of 200 amps, is only rated at 150 amperes in Table 310.16, at 60-degrees. The diversity built into the calculation is the reasoning behind this Table allowing to seemingly overload the conductors. If a Meter-Main combo is used with feed-through lugs, no circuits may be fed from that outside panel to the dwelling and still use Table 310.15(B)(6).

If the feeder is not the main power feeder, then Table 310.16 must be used and the 60-degree ampacity must be adhered to.

Hope this helps, if further assistance is needed, please contact me.
Thanks,

Ron

Ron,

I have a house with a meter with a service disconnect outside with SER cable running from the disconnect to the inside panel box, does article 334.80 apply to the wire from the disconnect to the sub panel box inside the house for derating to 60 degree?

Thanks
