No ground wire???


Recently moved to a house built in 1961. When replacing outlets found that there's no ground wire, two wires only. Boxes are steel and I think there's metal conduit in there. Is ground provided by the screws holding the outlet in the box? Effective? I would assume only if the conduit is grounded?

Have a newer box with circuit breakers and a lot of Romex coming out but not to my two audio outlets.

Any comments or opinions would be appreciated. Considering having an electrician run a new line for audio (which wouldn't hurt in any case). I would be more comfortable with a separate copper ground wire. All y audio stuff is three prong.

Absolutely have an electrician run a new, dedicated line, or maybe two, just for audio. It usually cost less than $100, and is one of the best bang for the buck upgrades out there.

Use at least 12 gauge wire and 20A breakers, maybe 10 gauge if you wish. You could even put in some new receptacles while you at it. You could go with fancy, Furutech, Oyaide, etc., but even less expensive models like Power Ports will make a nice difference.

Cheers,
