I had a similar problem working in San Diego. SDG&E insisted that no taps could
be performed in an enclosure unless the contractor could supply documentation
that the enclosure was specifically listed for a tap, or if an electrical
engineer supplied stamped drawings of the tap. I never did a project that
warranted hiring an engineer, so I don't know what they were looking for there.
I heard that Square D (or maybe it was one of the other companies) has a new
"solar-ready" service panel with a lug on the line side for a solar input. You
could use the same feeders and service size with a new panel.

Subject: [RE-wrenches] Line side taps in Hawai'i
Aloha Wrenches,
I have recently started working in Hawaii on the island of Oahu and have run
into some interesting problems with the AHJ's. The biggest issue is nobody is
allowing line side taps on the island, so most of are larger systems are
requiring service upgrades, this also requires replacing the feeder of course
and plenty of trenching which adds so much time and cost to the whole process..
Now I know Bill Brooks was on island recently and and this seems to have done
no good. I was wondering if anybody can shed some light on this issue and the
reasons why they would not allow this code compliant option. This is allowed on
commercial systems here just not residential to be clear.
And If your out there Bill, do you have any suggestions on how to approach
this matter with the local inspectors???
Mahalo,

Don't get me wrong: I love nuclear energy! It's just that I prefer
fusion to fission. And it just so happens that there's an enormous
fusion reactor safely banked a few million miles from us. It delivers
more than we could ever use in just about 8 minutes. And it's
wireless! - William McDonough
