Found the xformer grnd hanging behind a relay unconnected. The gas valve was the last component in line and had enough voltage to open the valve. Are you saying a poor chassis ground on a 24 VAC causes your circuits not to funtion properly? Are you sending current through the chassis? Never saw that, circuit boards always worked just fine for me.The 24vt is ac, without grounding it can back feed to grnd and cause, in the case I had the gas valve to energize on a call for heat, bypassing ignition and safeties, old Trane rooftop. I have had gas valve open with no safeties because of loose or disconnected 24vt grounds, solid state controls intermittently not function and other fail because of inadequate grounding. Most people die of electrocution from a 120 VAC circuit that has lost a path to ground (neutral).? We run 765,000 VAC in transmission lines to lower amperage and wire size then just drop VAC as necessary thru transformers. Edison lost because he was completely wrong and wanted to use DC. Edison was in a war with Tesla about electrical distribution. You are confused about the American 120 VAC system that uses a neutral instead of just using 240 VAC system like Europe. if the secondary goes to ground it is screwed down to grounded metal. The only transformers that were grounded on the secondary side I had to replace because some electrician thought everything needs to be grounded! Don't ground low voltage secondaries! Why would you want to ground L1 or L2? You do not ground live wires. Most people die of electrocution from a 120 VAC circuit that has lost a path to ground (neutral).

I need to ground the secondary 24 volts side, but there’s no indication on the transformer or from the manufacturer on which one of the two wires coming out of the secondary side of the 24 volts to ground. I’ve got a 120volts to 24volts transformer. If you have any problems with the registration process or your account login, please contact support.
