I have to jump in and remind you (as Deano did) that while a seperate ground rod may seem like a good idea, it is not safe due to ground potential between the two grounding points. In fact, it is against the National Electric Code to use a ground in this fashion. Driving an additional ground rod is ok as long as you ground the new rod to the existing main grounding point. Using a dedicated ground wire from the main grounding point (ground rod) to your dedicated hospital grade receptacles is the most effective and safe way to go. Be careful, a little hum won't kill you, but an unsafe electrical system will... Good luck & Happy Holidays
Really good home electrical wiring.
I am building a new HT room with 9 dedicated 20-Amp circuits and am planning on using WATTGATE's flagship 20-Amp receptacles. The one thing I am still unclear about is what type of electrical wire should be run to the HT room. I am most familiar with Romex because it is the standard for basic electrical wiring. I've been told that THHN Strand is much better than Romex. Finally I just have found out about the 8-gauge AC wire the JPS Labs sells. I am investing a ton of money into this room and want to use the best electrical wire. What do ya'll recommend?
