Power line question

Thanks! Sounds like this should not be a concern unless I'm blowdrying my balding head while listening to Metallica at a high volume...

The monoblocks deliver 150 watts per channel so 300 watts divided by the constant voltage of 115 equals 2.6 amps.

Thanks Meiwan. How do you determine the power consumption at a given time in a circuit? I looked at the hair dryer and it states volts, watts and Hz, but not amps. No such info is listed on the manufacturer' website either. The sticker on the breaker panel says "Mains Rating 125 Amp Max." I assume this does not mean my apartment. The only thing that would be in use while I listen would be the refrigerator, laptop and the TV set, most likely.

Ska_man, the monoblocks are the Rogue Audio M-180s.

Elizabeth, it appears the apartment gets 125 amps total based on the sticker on the breaker panel. This makes sense as there are eight breakers (four of them locked in pairs).

Thanks guys; this helped a lot. I certainly understand much more about circuits and power usage now.

To go back to Elizabeth's advice, my breaker panel actually lists which circuit powers what in the apartment, so they did the job for me. Interestingly, the oven has a twin breaker of 40 amps, the dryer a twin of 30 and the AC a twin of 20 (two switches each but bridged so that operate as one). It appears the lights in the apartment (judging from the list, this includes the power outlets), have a circuit with two separate breakers, each stating 15 on them. Does this mean there are actually two circuits of 15 amps each? Funny how fascinated I am now by the topic. I just might talk an electrician! Thanks everyone.

Jea,
I think I do. Here's the breakdown:
40 amps (bridged twin) for the oven
30 amps (bridged twin) for the washer/dryer
20 amps (bridged twin) for the AC
15 amps for the living room heater
15 amps (twin, not bridged - still confused what this means) for "lights." This one probably controls all of the outlets, but cannot test in now unless I want to incur my gf's wrath.
20 amps (twin, not bridged) for small appliances (fridge and kitchen outlets above the counter)
20 amps (twin, not bridged) for the dishwasher
20 amps (bridged twin) for the bedroom heaters

Not sure which one controls the bathroom outlets, however.

Do you really need a dishwasher? Ever considered a portable dishwasher? Frees up a dedicated 20A circuit... More cupboard space... You can sell that.

Ha, ha, indeed, I do not need one! In fact, it has never been used since we moved in. However, my dedicated listening room is the farthest room from the kitchen. It's not a big apartment, but I cannot run an extension cord from the kitchen to the listening room; my gf would never allow it and it would look ridiculous as the cord would have to be run through the living room. Re-wiring is not an option as it's a rental.

Sorry to be reviving this dormant thread, but I have some additional questions that I'd like to ask to solicit your opinion.

Is it possible to have a truly dedicated power line in an apartment building? It seems that one could rewire one of the circuits perhaps to only feed the system, but wouldn't that line be still shared with the rest of the tenants in a general sense? In other words, if a 20 amp circuit in my apt feeds small appliances in the kitchen, would using it for the system only be what people refer to as a "dedicated line"? Since other tenants also have that circuit and might be using their blenders and microwaves at the same time as I listen, would that mean it is not a truly dedicated line? How isolated are individual circuits in an apartment from other tenants' circuits?

My neighbor, who also happens to be an audiophile, had an electrician rewire his air conditioner line to 115V for use with his system. He calls it a dedicated line, which it most likely is during the winter months, but if the rest of the tenants living on the floors below him and in the rest of the building are blasting their ACs in the summer, wouldn't that affect his "dedicated" line?

Sure. Aside from that, are you saying that mine circuits are isolated from my neighbors' so that their usage has no effect on mine whatsoever? I noticed my kitchen light flickers barely noticeably sometimes; is that a sign of bad ac, heavy demand in the building, or something else?
Our power lines are underground and my audiophile neighbor agrees with me that we have a pretty good quality of current, especially late in the evening and at night for obvious reasons. I'm just exploring the benefit of dedicating a line in an apartment building with neighbors sharing walls and ceilings.
