I have the following equipment that is connected to a 15 amp dedicated power supply home circuit: 1. Two Sunfire Power Amplifiers - 1800 watts power consumption each 2. NAD 2700 Power Amplifier - 970 watts 3. NAD 2400 Power Amplifier - 390 watts 4. NAD 902 bridged - 240 watts 5. Sunfire Grand IV Pre-Amp - 40 watts 6. Cable Box - 55 watts 7. Apple TV - 19 watts 8. DVD - 24 watts 9. Sony DLP TV - 240 watts 10. CD changer - 10 watts 11. 2nd CD Changer - 15 watts 12. XM Radio Station - 10 watts 13. Misc other - 50 watts That is a total of 5600+ watts which, if I understand correctly, would amount to approximately 47 amps? I am having the house circuit upgraded and wondering if anyone can tell me what amp circuit would be recommitted to handle the above power consumption needs? Obviously I am not an electician and do not want to rely totally on the electrician's advise given that he may not be that familiar with home entertain needs.
