        The state of Washington has the following requirementFrown
        5
        ) All required equipment grounding conductors installed in concealed cable or flexible conduit systems must be completely installed and made up at the time of the rough - in cover inspection.

        Anybody know why?


        Do Well.

        Throwing a wild guess out that ground wires were skipped by the old timers doing the rough wiring. Requiring grounds tied together insures proper grounding will be present...

        answer: because it's code, and because it's easy to do when you install things, and a bear when you don't.

        everything that could be electrified has to ground at the ground bus in the entrance panel. the secondary ground in a metal-plumbed home is typically strapped to a nasty thick wire and terminated at the ground lug of the panel.

        ground is your friend. if something comes loose and hits a hot wire, ground is your friend, whacking off the breaker before it can start a fire or energize something like the water pipe, which will likely injure or kill somebody.

        ground is a friend that must be absolutely correct.

        hence the electrical code and inspections.


        sig: if this is a new economy, how come they still want my old-fashioned money?

        Still curious as Felix the Cat, wonder if your inspector can provide an explanation. Big Grin

        Sorry to take so long to get back to you. I asked the inspector on the latest go around. He said it was because some cities in WA do not require a final inspection. Making sure the grounds are made up for the rough in ensures "our friend the ground" is adequate at a minimum.


        Do Well.

        Grounds are required to be tied together here for the rough in inspection as well. On the final with the devices in you can't see the wires. I suppose they could verify the outlets are wired correctly with a 3 light outlet tester.


        General Disclaimer

        Any advice given here is general in nature and is not necessarily valid for your given area. If in doubt check with your local codes enforcement department for what is required when doing electrical, plumbing or structural work on your house. Permits may or may not be required in your area and home owners may not be able to DIY some tasks. I have no way of knowing if you have the skills needed to complete the tasks you are asking about, when in doubt seek professional assistance.

        My advice may be worth exactly what you pay me for it. :-) For the record I did not stay in a Holiday Inn Express last night.

        Interesting approach.
        Here on the final all pigtails have to be made up and about 90% of the devices can be installed. But say one box a room can have the pigtails made up but minus the device being installed. And the wire must be extended out of the box showing that the 6" rule of wire is present, allowing ample wire for future changes.
        Now this not a hard and fast rule but allowed by inspectors that you have a good working relationship with.
