Elec

Hey guys say your main service is grounded properly. And half of your house is run conduit. The other half is is run in the really old bx cable with the cloth insulated wire. Is the ground path from the service going to be be disrupted where the old bx connects to the conduit and or boxes?or will it stay undisrupted as long as all the connections are tight . There is no green ground or bare wire running out to any of the circuits. The service is grounded off the water pipe that goes outside. thanks.

First, you should understand that the grounding of the panel, and the grounding of your outlets, are two different systems, serve two different purposes, and do not rely on each other.

If there is a wire running from the panel to the water pipe where it enters your home, then your service is grounded.

If there is an electrically continuous path from your panel to your outlets, then your outlets are grounded. The old BX does provide some limited grounding, but it is not an approved grounding path and isn't very good grounding. Some of the quality of the grounding depends on the quality of the connections.

Why are you asking?

Should have been replaced? I guess it depends on what you and your electrician agreed to and what you paid for. You can discuss this with your electrician. He inspected it first hand when he was out there.
