Power Question

Currently I'm building a house and want to make sure I get the correct power for the the system I'm intending to evolve too: That would be 3 MC501s, 1 MC207, 1 MX119, 1 MS300, 1 MVP871, 1 MDA 1000, 1 Basis 1400 TT, 1 Satilite box, Plasma Screen, & 2 RGPC 1200's. I am thinking of getting two 20amp dedicated circuits. Is that overkill, underkill suggestions? Also, would it change much if I went with MC1201s.

This is a great question. I am in the same boat with similar equipment. New House/Basement soon. One additional question I have is what impact does the MS300 have on power requirements and or needed power conditioners (Since it basically is a computer).

Thanks

Certainly no room for expansion. :yes:

I would have a couple of more circuits installed especially since it is new construction.

I don't want to steal this thread but I am interested with the same topic.

I was thinking that 2 20amp circuits would be generous. Is that not enough. I have only one in my audio room now. Heck....it might be even 15 amps.

Any validity for having these installed?:

Always a good idea. A strong/tight solid connection will create little resistance.

I am a novice here also but I had read a dedicated 20 amp for each 501 was prudent?

MC-501's draw 6.6 amps each at WOT (wide open throttle)

Dedicated 20 amp lines each are excessive (listen to me, I had to look up the spelling of that word) however you can never have too many dedicated circuits, or too much current.

I always love explaining to the Engineers at the local power company why I need so much current.

I'm waititng for the NSA to show up one day, out of fear what I'm doing with all that Electric. :lmao:
 
BTW, Cape Cod really needs a Nuclear Power Station & I'm not kidding. I had to install an insane amount of voltage regulation devices. The power fluctuates all day & night. :yes:
 
what do the 1201's pull

the 501 6.6amps

Need to make sure i would be ready for them

lastly the amount of amps needed to run and realistically used are 2 different things aren't they ?

I have the equivalent of an american 40AMP dedicated circuit, but since its 230V its 20Amp

At 230 volts 1201's pull 7.8 amps @ wot

At 230 volts 501's pull 3.3 amps @ wot


MC1.2KW pull 6.5 amps @ wot :naughty:

Well I have 20 amps each and a third for the source.
What would you recommend I do to address the power fluctuations with such a modest system?

When you say power fluctuations, I assume you mean voltage fluctuations.

Me, I use & recommend Furmans AR-20 II voltage regulator. Quiet, precise & reliable. :yes:
 
Install Min. two 20 amp dedicated lines, one soley for your amps, the other for everthing else.

Also while your at it, and this is what alot folks ignore, be sure your two dedicted circuits are on one of the two down legs (buss bars) in your breaker box that DOES NOT have noisy devices on it....ie. refrigerators, dimmer circuits, A/C, flourescent lighting , etc. If need be the electrician can re-arnage at the time he is installing your dedicated lines
 
I have 2 dedicated 20 Amp circuits with the 501's and the equipment in my signature. Everything is dead silent and there is no question of enough amperage. My only regret is that I personally installed the second line after construction and it is hot, hot, hot in a Naples, Florida attic in the summertime. You could even have a couple of unconnected extra lines run now in case the LuFlu forces you to move to tri-amping with the MacKW's in the future.

Ivan,

Whoa.......

It says in the specs that both the 501 and 1201 need 15amp line, but according to what you are saying Ivan at 7.8 Amps at 230V is equal to 15.6 Amps @ 115V so that surpasses what they list.

Can you double check that figure. It seems high ??

You need to halve what ever it is in 115V to have the figure =

I'm trying to make sense of the difference between the 501 and 1201. I know looking at the size of the beast it is considerably bigger, but the difference in power usage is enormous.

Whoa

you r da man Ivan........

If I get a pair they would actually be 240V units meaning they potentially could pull 7.5amps each.

The 1.2kw are more efficient and more attractive because of that...

A 20amp @ 230V fuse may not be enough for 2x1201 1x501 1x252 and the rest processor, cd player, bluray player, tv and 2 satellites. The 1201's alone need 15 amp

what are they really using amp wise at 70 db's. I don't push these and probably wouldn't need to
