Newby question about amperage

[Ranger Mike]

I'm going to finally get a SS system. I'm thinking a Yamaha rv-x659 7.1 and a velodyne decco speaker set. My problem is I live in a trailer. I only have 30 amps total for everything. 1-5 amps go to the converter, about 13 amps to the AC (I live in the desert), plus lights and the TV etc. I'll have 7 X 100 watts for the receiver and the subwoofer has a 600 watt RMS class D amp.
Will I have enough amperage to handle peak current needs?
Thanks

I would suggest going to Yamaha's website http://www.yamaha.com/yec/ and downloading the manual for the receiver you are considering. The manual should list the power consumption (although it may be an average consumption, rather than max). That should at least give you a good ballpark figure. Do the same for the subwoofer if possible.

I think you would be alright as you aren't going to require peak load from all sources simultaneously.

Power (watts) = Current (amperage) / Voltage

Current (amperage) = Power/Voltage

When you find out the Power consumption of the sub and reciever (it will say on the back) add the amount of wattage up and divide it by the line voltage 115-120v in this case. You now have the current draw of the components in amperage. I suspect when the AC kicks in that your lights flicker, Is this correct? This can sometimes be enough of a drop to turn off your reciever. So be carefull.

Thats a hard one not knowing the full amount of draw on your system as it stands.
The receiver according to its specs from what I saw will draw 4 amp at its max, but the AC while it runs at 13 amps will pull more on a restart of the compressor.
You have the fridge to consider kicking on and off, the AC's 13 amps, 5 maps to the convertor, dont know your TV's type and its draw, but your over 20 amps with convertor, AC, fridge and do you have electric hot water???? Amongst other things???

If it was me, I'd be very careful to the point I had a secondary breaker of another 20 amps or so added. Your power feed line to the trailer probably could handle 100 amps no problem,its just your running a small breaker arrangement because its a one floor trailer which wouldnt normally consume over 30 amps on average. I lived in one when I first got married and thats what I did was add a second breaker to be safe. Now I got a 200 amp 3 phase breaker and still run a separate line to my HT area!!!

It won't be an issue as long as you don't have everying running at the same time, and blasting your system. To get the most efficient system, check out Panasonic's digital receiver. It's very efficient and provides a good deal of power to drive most 8 ohm speakers.

The class D sub amp is efficient as well.

Ranger Mike,

I'm sure you've seen this, but Clint seemed to love the Deco system, especially the subwoofer.

"""Will I have enough amperage to handle peak current needs?""

I think that was the key phrase!!!!

And going to the Panny is backwards from his Yamaha idea.
Oh sure those digital maps are more efficient, but 135 watts average useage, at 7 channels might be a bit less than he was looking for!!!
