Grounding Electrode Conductors

Does water also flow through this machine?

nope, no water flows through it.

Honestly........it sounds like some of their engineers need to work themselves out of the book. As others have stated it sounds like total BS and that they are trying to solve a theoretical problem.


Post back what you find out/end up doing.

I'll call them back... i'm thinking i'll call the general number for the manufacturer, perhaps i can talk to tech support and they can guide me to one of their engineers. I'll keep everyone posted.

I thought it was a great idea at first, but the water itself would complete the circuit. Ions flow though the water between dissimilar metals.

I'm thinking i will ask them what has been done at other sites. I'm sure the hospital where we are installing this machine isn't the only location. I'll come back with what has been done at other sites.

It has been my experience with a few medical equipment manufacturers that they have no clue and this outfit sounds like a perfect example of one of them.

It is possible but considering this comes from a medical equipment manufacturer he probably heard them correctly. We had one manufacturer that told us we could not ground their equipment, of course we told them too bad and installed them per code then tested the room per NFPA 99 equipotential requirements. When they would come back to commission their machines and would lift all the EGC connections, claimed it caused a multitude of problems. When the local authority found out they shut the machine down and had the manufacturers installers schedule to have all their other equipment shut down so they could inspect each and every one regardless of the machines function, MRI, Cat Scan, Cath Lab, etc...

After that they got on board and believe it or not, they didn't have any problems.

I agree, they are wrong, find a way to train them right. Then send an huge bill for consulting fees, which they should understand because they are selling med. equipment and are firm believers in charging a high price for their "expert" services.
