Wrenches, As a follow up to my last post on multiple subarray wiring methods I'd like to hear opinions on running bare copper ground wires inside EMT.
The following Galvanic explanation and chart would seem to indicate that it is not acceptable which is always what I've been taught: http://www.engineersedge.com/galvanic_capatability.htm However, I inspect PV installations on a regular basis and commonly see bare copper in EMT with no significant signs of corrosion. Maybe they're not old enough? Thanks, August August Goers Luminalt Energy Corporation O: 415.564.7652 M: 415.559.1525 F: 650.244.9167
