[RE-wrenches] NEC 230.46 spliced and tapped conductors

[August Goers via RE-wrenches]

Hi Wrenches -

Occasionally we will do supply side connection for our PV systems. As of
1/1/2023 in CA, we follow the 2020 NEC 705.11 Supply-Side Source
Connections section. Recently, an inspector asked us to comply with the
following:

230.46 Spliced and Tapped Conductors
Service-entrance conductors shall be permitted to be spliced or tapped in
accordance with 110.14, 300.5(E), 300.13, and 300.15. Power distribution
blocks, pressure connectors, and devices for splices and taps shall be
listed. Power distribution blocks installed on service conductors shall be
marked "suitable for use on the line side of the service equipment" or
equivalent.
Effective January 1, 2023, pressure connectors and devices for splices and
taps installed on service conductors shall be marked "suitable for use on
the line side of the service equipment" or equivalent.



When we reached out to one supplier of insulation piercing connectors
(ILSCO), they responded: "We are still in testing, I just checked and from
what I see there are no products listed for this new requirement yet by any
manufacturer."

Has anyone bumped into this before and/or have any proposed solutions?

Best, August

Re: [RE-wrenches] Solar and tenant billing

[Christopher Warfel via RE-wrenches]

There are quite a few utility grade submeters out there. Leviton is one, 
and here is a link:

Usually a utility will not let you distribute renewable energy to more 
than one meter, but some programs allow this, so I am just mentioning to 
make sure this can happen. In any case, these meters will give you an 
inexpensive way to know what each tenant is using.

Hello wrenches,
I have a client that is installing solar on a commercial building 
where he has four points of connection for four tenants.  Are there 
any good solutions out there for metering power for tenants in this 
situation.  Production metering will be done via  SolarEdge revenue 
grade meters.


With kind of regards
