A 120VAC/20A circuit is appropriate for a lot of things.... a 1500W HF amp is not one of them.
Just do the 240 circuit... http://montac.com/images/shack_power/outlets.jpg https://www.dropbox.com/s/67hjpy126yr48sg/2016-08-28%2009.51.14.jpg?dl=0 https://www.dropbox.com/s/16iflr76lvwe88c/2016-08-28%2018.19.38.jpg?dl=0 https://www.dropbox.com/s/bkz0k60nzzsg1y0/2016-07-28%2018.29.45.jpg?dl=0 https://www.dropbox.com/s/92jeckuevh9t8j2/2016-07-27%2015.28.52.jpg?dl=0 Twisted pairs, steel conduit from service to sub, sub, to outlets, 240VAC/60A sub-panel, 8 x 120VAC/20A, 2 x 240VAC/15, 2 x 220VAC/20A Just find an electrician who will inspect/sign off on the work. ______________________ Clay Autery, KY5G On 4/20/2017 3:14 PM, Dauer, Edward wrote: > It might, but at typical efficiencies 1500W peak output would be a > significant draw on the existing 117 VAC wiring – likely over 20 amps.
