installing new UPS for my office and needs electrical work...

I own one of those at work. You WILL need to find out what the AWG size of your wiring is to your plug. You will need to make sure you can carry 30 amps of current. I'd bet money you will be upgrading. Nobody uses thick 30 amp capacity cabling in walls without putting in the 30 amp plug. So short answer is yes, you will need to run thicker cabling in your wall (most likely). You will also need a bigger breaker.

In all seriousness, there's alot that you could do wrong and pose a serious fire hazard. If you're ready to make the jump call an electrician for an estimate before you buy the UPS. This will all make sense to him.

"Field trials in the summers of 1994-98 at Langmuir Labs have provided electric current measurements flowing from various shaped lightning rods. These were correlated to changes in electric fields caused by lightning discharges. Results of this work confirm earlier theoretical models about sharp vs blunt rod behavior. (3) Sharp rods are poorer receptors for lightning than blunt rods."

Again the point. In many fields where knowledge comes mostly from hearsay: what is popularly believed (without numbers) too often does not agree with reality.

OK sounds good. now I need one thing definded. What are we considering a "blunt" rod? Are we talking a rod where the end is like a half sphere or a pointy rod that is NOT sharp.

For example hehe:

:ROTF: I couldnt resist!:p:

the reason i need the details is because i will end up making my own out of stock rod. Thats why I was asking about solid vs braided and such. Hell if i am going to pay someone thousands of dollars to do something that i can easily fabricate myself once i have the details. :up:

Good question. I always only considered straight rods. However the reasons behind Dr Moore's study implies a 'balled' rod would work as good; probably better.

Well there is going to be a brand new breaker box inside the server room and yes the size of the wire will be accordingly to the 30amp outlet w/ dedicated line. Its pretty much a dedicated breaker box also just for the server room. There might be 3 lines in it at most -one 30amp for the battery backup/UPS system (it will provide power to the PoE network equipment which in turn acts as a power source for everything and anything connected to it -ie. PoE cameras, etc), and 2 x 15 amp lines for anything else in the room.

Yes, I already contacted an electrician to get a basic understanding of everything including all work that needs to be done and the various options. We decided to go with the idea of a dedicated breaker box just for this room - data/server room, a whole house protector (not decided if its going to be 150k amp or higher yet)

But we already bought the UPS and that was my mistake although its almost a year old now since we purchased it, the most that could go wrong with it, is the battery. It might need some advanced diagnostic testing before we can use it since we never turned it on for this past year.

Actually that raises another question, so in terms of the server/data room. The new breaker box and whole house surge protector as you know is going to be in here and it will be I would guess at this point a couple feet away from all the equipment. We can move it further away if needed because the room is of a fair size.

So then with the optional rods the electrician said we could have, and we probably will go with a couple of these, how many exactly should we get and where would they have to be placed and also about the tops, rounded (balled) or pointed?

Not sure if your response to little scrapper was referencing outside placement of the rods or inside.

also little_scrapper here is some better pictures of them:

and since we are discussing the rods now, Tellurium Copper vs 99.9% Pure Copper ???
