Dick, colleagues:
I was at a seminar in which John Wiles lectured building officials and
installing contractors. At one point I asked about 690.31(E) (2005). Mr.
Wiles glibly commented that the restriction of that section to
utility-interactive systems was a "typo" in the 2005 edition. There were
many officials present that inspect and plan-check my work. Based on Mr.
Wiles remark, several inspectors have been trying to apply 690.31(E) to
off-grid systems. This has cost me time, money and aggravation.
Mr. Wiles apparently does not know the responsibility he has when he makes
off-hand remarks. His opinion that a given passage in the code is not
correct does not negate what is in black and white. With all due respect,
I wish he would be a bit more temperate in his remarks.
Sincerely,
William Miller
PS: Mr. Wiles showed slides of his home installation. It may be a code
complaint installation, but there is nothing pretty about the
workmanship. I think a thorough familiarity with the code does not alone
comprise a complete education on PV installation.

According to John Wiles, the code making panel for 2008 Article 690 was
disbanded
by the NFPA because it, "violated NEC code developement procedures and
because
of other issues." Doesn't leave one with much confidence in their work.
