Not sure of the R-value on my insulation. I can tell you that it is standard roll out insulation designed for metal buildings. Approximately 4" thick. --Intermittent Heat --Door seals are very good --Shop is mainly used for hobby type work + a little ping pong and dart throwing with my kids...

These are the 4 that I am considering. Is it better to get the 240V or the 480V? Thanks, http://www.globalindustrial.com/p/hvac/heaters/electric-unit/industrial-electric-horizontal-unit-heater-7-5kw-480v...

I know this has been discussed at length in several different threads but does anyone have experience/advice on using one of these in a larger shop? My shop is 30x40 rigid metal contruction with insulation, 20ft. insulated garage door and two 24X48 Pella double pane windows. Any guidance is...

That answers my question. Thanks for the info.

I am not confused with the difference between neutral/ground. I am asking if the ground (green wire) should be attached to my 4" metal boxes.

There will be spices in many of the overhead boxes. If I am understanding you correctly, if there are splices in the boxes then I need to ground the box to the ground wire going back to my breaker box. What about the boxes that house the outlets at the end of a "run"? There will be no...

I am wiring my 30x40 metal shop with new 200 amp service. All wiring is in 1/2" and 3/4" EMT to 4" metal square boxes. My question is am I required to ground each 4" metal box (to the ground wire running to each box)?

Talked to my code enforcer today and he said it was fine to bury the grounding rod in the ditch with the service wire/conduit.

Thanks Speedy. I talked to an electrician in my area today and he said that I could put the 8' grounding rod in the trench with the main service line (since I am unable to drive it in with the bedrock issue). Others have referred to doing this but is it against "code"?

Tried jack hammering grounding rod in two different place. Went about 3 feet down with ease in both places and then to a dead stop. Guess I will call the code inspector on Monday and see what other options he will let me do.

Thanks for the advice.....rented a jackhammer this evening to hammer out the rest of the rock for the 3" 90.....will try to jackhammer the grounding rod tomorrow.

Thanks BillK.

Yes...he said it was only an additional bonding for the building and that I still needed a grounding rod. My builder did weld the rebar in the footing to a vertical rebar that the inspector placed in the footing upon inspection and then he welded it to the building....does not sound as...

2011....my building was bonded to the rebar in the footing but as I understand it I am still required to have a 6' grounding rod.
