Maybe I am behind the times. I have not installed cable between buildings for several years.

My employer wants me to install direct burial cable attaching it to an already existing span with cable ties. They won't purchase a cable with a messenger. But that is not the worst of it.

They don't want to install a ground stake with a #6 cable coming from the protector. I don't think thay will even want to bond and ground the shield.

They want me to terminate the pairs to the protector and then run a ground wire (#10 I suppose) from the protector to some kind of an adapter that plugs into a 110VAC outlet and which supposedly only has continuity with the ground terminal at the outlet. Of course this would send a lightning strike through who knows where in their customer's building

Has anybody ever heard of such a thing?

This idea seems absolutely wrong and very unsafe
