Video/Audio Amp Power usage?	Can't Post

Am in a pinch for info regarding Video/Audio Distribution Amplifiers. I am setting up my circuitry and need to know what the current usage is for the Kramer "VM-5ARN" AND the "Comprehensive Video Group/Kramer CVG-10A" Video/Audio Distributors. I am running several VHS machines as well and am worried about overloading the Electrical circuit I want to connect to when I fire all these monsters up at the same time. My Wattage for everything, less the AMPS, is a total of 320 W. Do I need a higher than 20 AMP line to handle this??? Help,?? or..... can someone call the fire department if they see smoke coming from my place, please??? They are both 110 Volts power, but the usage watts has me baffled.

Would appreciate any help you can offer, nothing, so far, can be found on the web with their specs for these units.

Lisa, you can safely hook everything up to a single 15 amp household outlet (using power strips as needed).

Here's the math: Power (watts) = Voltage X Current (amps). For AC, use 120 x.707 = 85 volts (average)

So, 320 watts (plus maybe 20 for the DA, plus a little in reserve) gives us a load of, say, 350 watts.

350 = 85 X I, or I = 350/85 = 4.12 amps. That's WELL within your breaker's capacity.

I have been running 30 VHS decks, 2 DA's, a couple of full size digital decks, a couple monitors and a 30" TV all simultaneously from a single 15 amp outlet for years.
