Hey there everybody. Having a little bit of trouble here. I'm running a 20 amp line from my panel to my garage. This is how I ran my circuit. Power from panel to a regular outlet, then I ran three gfci outlets for outdoor. I have a hot and neutral wire only running from panel. Now for the gfci outlets I grounded them from the water proof box. First regular outlet is not grounded to box. When I test the outlets my tester reads open neutral.I've checked all connections and then double again. Can anyone tell me where is the problem here?

What size/type wire did you run from the panel to the first outlet? You can install one gfci outlet and feed the other standard outlets from it.

Which is it? Open ground or open neutral? You state both.

If you only have two wires, hot and neutral, an outlet tester will report an open ground.

If you just installed this wiring as new, why only two conductors, and no equipment ground? There should be no reason to be missing an equipment ground.

Are you sure the waterproof box is grounded? How is it grounded?

I'm sorry. It reads open ground. It was my understanding that when there is only two wires hot and neutral the conduit is the ground. The conduit runs to the service panel. So then would I be wrong?

I thought the same think as TK, then I noticed the OP is in Ill. conduit country.

The conduit might be compromised somewhere discontinuing the grounding path. This is why I ALWAYS run a grounding conductor regardless of the type of conduit.
Also, did you connect a jumper from the devices to the boxes?

Well guys, I'd like thank you guys once again for your input. I've learned something new today. Always run a grounding conductor regardless of the type of conduit. TK my outdoor outlet boxes where in fact NOT grounded properly. This is why my tester read open ground. Thanks for your input. This is why I love consulting ASK ME HELP DESK. Thanks again.
