Out my way...

We're required to paint/mark OUR seismic wires differently than the grid crew.

Beyond that, we're required to run wires to even the dinky fixtures.

This all goes back to a Southern California earthquake caught on security tape. The retailer had been built without seismic wires for the fixtures. They ALL hopped up, out and down onto the shoppers below... after which the hot connections popped open. ( The only remaining support being Greenfield )

Thusly, I've ended up being forced to install wire.
