Consider the purchase of a 'Kill-a-Watt'...an external, plug in power meter. It will give you Volts / Amps / Watts and other data, including hours and Watthours.
So, instead of reading back plates of equipment, you will be able to measure stuff and see. Even a hi power amp won't draw much current if not pressed. If pressed and the current capacity of the circuit is insufficient, you may see a voltage drop or sag.
Another measure is 'Power Factor', which for most gear is very near 1.0, meaning that current and voltage neither lead or lag one another. This is good.
The cost? I found 'em at Fry's, a local HUGE SoCal retailer for all of 20$. Other power measuring equipment has up to and including, a USB port to connect to your confuser. They are pricey and to me, vast overkill.
Let us know what you MEASURE.
