[RE-wrenches] supply side connection - Tap connector recommendations

[Jason Szumlanski]

In some jurisdictions and for some utilities, pulling the meter is a MAJOR
ordeal. Some jurisdictions require a "service change" permit on top of the
solar permit just to have the meter pulled. It also requires getting an
inspector out there at the perfect time to have it inspected so the the
utility will re-install the meter. The homeowner is often without power for
several hours, which is usually somewhere between inconvenient and
unacceptable. Insulation piercing taps are extremely common around here for
these reasons. With proper safety precautions and experience, I don't see
any issue specifying and using them.
