I'm considering adding a mobile type amp in my radio setup. I like the mobile to use both mobile and on my base with a power supply. Question is amperage. I'm looking a 150 watt amp. The power supply for my radio (it's a mobile I also use as a base) is 4.5 amps which I know is not enough to work both. The wall socket that I use for powering the power supply is only a 20 amp circuit. If I buy this mobile amp, is this a consideration when purchasing another power supply? I guess I'm asking if I were to purchase a huge power supply putting out 30 continuous amps, it would blow my house circuit breaker once turned on. Right so far??? would a 15 amp power supply be workable for 150 watt amp? |

That is 30 amps at 12 volts...at 120 volts it is only a few amps and would not blow the house fuse..

divide 150 by 120,that'll tell you how many additional amps that amp. will draw on house wireing,oh add the wattage draw of P.S. to the 150 figure.On a 20 amp circuit you should be able to run a 100 watt trans.driving a 1600 watt amp,just get a big enough P.supply,the lights will blink a little but it's great effects on halloween. |

Thanks 307, had to pull out the book I'm studying on electricity (imagine that huh!) to figure out where you came up with that one. 12V vs 120V made sense. I appreciate your response. Now I understand.
