HELP I think I have an electrical issue??

I know not all hospital outlets are not isolated. Most people here who are installing hospital grade are doing it for the isolated ground and unless wired correctly it will not be or can hurt someone. When an electrician or home owner installs it and does not use the correct wire it is a waste of time & money. You must bond grounds.

Sorry Hevac your post is a little confusing. I am sure you are aware Hospital Grade receptacles are made either isolated ground,(IG), and non isolated ground type. I would venture to say the majority of hospital grade recepts used for typical home audio equipment are not IG type. Example is Albert Porter's Porter Ports. A NASA cryoed Hubbell HBL8300H duplex receptacle.

As for Tmesselt case if he paid the extra bucks for a good quality IG hospital grade recept, say like the Hubbell IG8300 he can still use the recept for its great build quality and sonic benefits it may yield for his audio system. As for the equipment ground I assume the dedicated branch circuits are 2 conductor/ with bare grd NM-B sheathed cable. Did he waste his money buying an IG recept in his case? Yes....

As you, I am aware of NEC 2008 Art 406.
You might want to refresh your memory... 406.2 (2)
=========

If the recept has a ferrous metal yoke he could always use a stranded wire grd pigtail from the yoke, strap, to equipment grounding conductor of the branch circuit. That is if he thinks the ferrous strap is affecting the sonics of his audio system. Brass un-plated strap... there would be no problem jmho.

I said I knew about the IG and non IG Hospital grade outlets. I will depend on what and from whom they purcahase the outlet from the PS Audio Power Ports are IG.
How electrical is run and is terminated will differ from state to state and the NEC is a referance for states to write there own. Some states are more lax on the NEC rules, some are not and some add rules. MEC and not the NEC is what I have to go by.

Here in Mass home owners can only pull wires with an electrician (for now anyway) but not terminate no matter the voltage, legally anyway. Not even a thermastat or doorbell.

In NH you run and terminate as long as you own it.
Your state may be differant then mine is.

Jen48,

I called my inspector today and asked him why I had to change the pastic boxes to metal on the IG outlets on a job he inspected for me 2 months ago. I am putting this in layman terms. If there is any METAL on an outlet not used for powering the outlet it must be grounded no exceptions.
He also said if I could find an outlet without metal tabs for mounting then the way I had it would have been fine.

Do you know of any?

Sorry if I blabbed or you thead Tmesselt.

I am putting this in layman terms.

LOL, not for my benifit I hope?

AHJ.... He has the final say.... Did you ask the inspector if he would approve a bonding strap, wire, from the yoke of the recept to the grounding conductor?
Curiosity killed the cat... You are an electrician, why were you using an IG recept on a non metallic raceway installation?

As far as NEC 2008 406.2 (2) if a non conductive cover plate is used it is ok to use the IG recept.
We don't know what the AHJ would have to say where Tmesselt lives.

Curious where did you read in Tmesselt's responses where he said his hospital grade recepts were IG?

Layman terms was not for your benifit but for others.

I asked before and was told Metal box only allowed.

Too much metal for a home too afford. BX not allowed.

Differant state rules.

I asumed it was IG.

Will email to explain further.
