@immatthewj The Furman specs for the 2400 are:
10 ft. captive 3/12 AWG, black cord with NEMA 20 plug. Mine is still gathered, as I only needed 3 feet, but would think 10’ is accurate.
AC Power
I have a relatively nice system, but have done nothing with my AC power, with the exception of upgraded PC’s and a cheap iFi plug in power conditioner. My question is multi fold… do I need to do something, and if so what? Dedicated line (15A or 20?)? Quality power conditioner? Both? Which one first? How do you tell?
My system is a combination of HT & 2 channel & I tend to use both simultaneously as I like to watch sports while listening to music.
My amp is (I think) a relatively low draw… Moon 330A, Rythmik sub, BHK pre, Aurender, Qutest w/Sbooster, R11’s. No high power amps are in my future & never listen above 75db. I do currently plug my amp directly into the wall. All my wall warts are gone. For my HT, add a 75” Sony TV, Marantz 7015 AVR & a Klipsch sub (although at zero volume the AVR & sub should not come into play).
I am considering buying the Furman IT-Reference 15i or 20i first as they are well reviewed & are priced very well on Amazon ($1,400 / $1,900). Before I pull the trigger, should I go dedicated power & at what amperage (my nephew, an EE & audiophile thinks I am drawing no more than 5 amps) as that will dictate the Furman model?
Interesting, my nephew thinks neither are worth the investment. His statement: “Do you have appliances on the circuit now? What kind of interference can they inject?...voltage drops would come from current draws...which trip breakers.
Not steady 60hz a good power supply handles. So it all comes back to was the power supply engineer dropped on his head as a child.”
”Personally I think it’s something audio people do when they have run out of gear to buy.”
Any thoughts or recommendations would be appreciated. Thanks!

10 ft. captive 12/3 AWG,
@signaforce define gathered. I would not coil the the remaining 7ft in a neat tight small diameter coil. Imo, a small coil would act as an inductor. FYI do not cut off the cord to make it shorter. That more than likely would void the Furman 2400 warranty. Just a guess, I could be wrong, the length of 10ft cord may be for the proper operation of the type 3 point of use SPD, (Surge protection Device) inside the unit. With a type 3 SPD the minimum length of the branch circuit wiring from the electrical panel to the SPD matters. The minimum length is 30ft.

Thanks @signaforce and @jea48 . |
@jea48 - Of course, always follow the rules, but the 30’ requirement AFAIK is to avoid excess current that is too high for the AIR (current interrupt rating) of panel breakers. This is a problem for parallel based surge protectors. Furman, when labelled SMP, are series mode and limit current. The cord length is a convenience for professionals who often mount them in portable racks. You kind of answer your own question here:
IOW, the length of the SPD’s cord is irrelevant to the 30’ requirement. Furman does make less expensive models which are not labelled SMP, which use plain old MOV's. |
