Total 'current' usage of a HT system

[JimTW]

Hey folks,

How do you calculate the current draw of your entire ht/stereo system?
Do you just try to find out the current draw from each component (amp,
preamp, dvd player, cd player) and add that up? I need to figure out if
1 outlet (2 sockets) will be able to provide enough juice for the ht system.

Tks!

You don't need to "try" to find out the current draw. Every component has the maximum current draw/power consumption (amps, volt-amps or watts) listed, usually on the rear panel of each component. I just total those up. Unless you have a massive, current-hungry amp(s) and elaborate HT system, a single 20A circuit should be just fine. Some folks will suggest separate circuits for your analog and digital components, which is okay too. For years I've run separate 2-channel and HT systems each off a single 20A circuit with no problems.

I remember seeing a post a while back of a handy device you plug in to your outlet, then plug your component(s) in to it and it gives a digital readout of power consumption.

Try searching or hopefully someone will pop in here that remembers the device

Is it the Kill-A-Watt power usage meter ?

Thanks guys for your responses. I've added up some amp ratings
for the different componenets and will try to keep it under 20A per
outlet. Thanks!

Here is the formula: 1 Watt = 1 Volt * 1 Amp
Add up all the watts and devide by the volts.
