1. [Amps] SB220 on 120V (score: 1): Author: Dick NY1E <dick@ny1e.com>; Date: Mon, 4 Apr 2016 01:05:59 +0000 (UTC); Hello list, I've had an SB220 in the past and am looking for another one, but I will have to run it on 120 volts, How does the 10A breaker handle the change? I've never heard of anyone changing the; /archives//html/Amps/2016-04/msg00001.html (6,705 bytes)

Re: [Amps] SB220 on 120V (score: 1): Author: Bryan Swadener via Amps <amps@contesting.com>; Date: Tue, 5 Apr 2016 16:32:48 +0000 (UTC); Hi Dick, According to the SB220 schematic, each circuit breaker feeds one primary winding. IOW, just fine. The problem is, you need a STIFF 120V source to avoid dynamic instability of the HV. My SB22; /archives//html/Amps/2016-04/msg00004.html (8,000 bytes)
4. Re: [Amps] SB220 on 120V (score: 1): Author: "Roger (K8RI)" <k8ri@rogerhalstead.com>; Date: Wed, 6 Apr 2016 01:10:43 -0400; 10A is pushing your luck. That's 1200 Watts total on that circuit and the wire for a 10A circuit will give plenty of voltage drop under load. All my 120 VAC circuits are either 15A, or 30A with appro; /archives//html/Amps/2016-04/msg00005.html (8,572 bytes)
