Hi All,
I just finished running the power to the Spa Sub-Panel that supplies power to my semi-Kal Clone EHERMS control panel, and I just started energizing/troubleshooting my build, and like A-Rod, I'm striking out, and need some help. I started asking questions in another thread regarding GFCI Spa panel wiring, but figured I'd start a seperate thread to keep from hijacking the other, particularly when PJ responded, and asked for some pics and more details.
The problem: When I turn on the primary power on switch, I trip the GFCI.
The facts: As mentioned, Im building a modified Kal Clone with 3 PIDS and a timer, an overall on/off switch that controls the primary power contactor, and includes a PJ E-stop fuse/resistor circuit. I'll include some figures in the first few entries of this thread, and as many facts as I presently have, so all of you McGiver's and Sherlock EHolmes out there can point out what I'm doing wrong.
The first figure shows my power feed schematic, where I have a 2pole 50A breaker supplying the standard HD Spa Panel. Just about all of the components are new (the stainless box, heating element outlets, and other connectors were salvaged).
The second figure's my overall wiring schematic ( I wish I could figure out how to get put the text in between the figures, but when I uploaded the figures to the gallery first, I just got thumbnails)
The third pic is of the SPA panel. Power comes into the panel on the bottom left (6/3 copper). The two hot legs (R & B) and the neutral (W) go into the appropriate terminal blocks, and the ground goes to the ground bus. I use the 2 pole GFCI breaker in the SPA panel to feed a 4 prong range outlet (with neutral and ground). I also added a 15A SP breaker to power the fans and lights in my exhaust hood, and a range cord hard wired into my panel provides the power, shown in the 4th. Sorry about the ugly wiring, but that #6 solid copper's tough to work with, and the flex/extension wire for the lights and fans is temporary, until new walls get installed and the boxes get permanently mounted.
The bottom picture shows the panel front, and my main power switch is top center on the panel, and is an Auber maintained, lighted selector switch.
Details: The power to my control panel comes from the SPA Panel through the range plug. The two hot legs go one side of a 240V 2 pole contactor (with 120V coil). I tee off one of the hot legs to go to the illuminated auber maintained selector switch, as shown in the first schematic. When this switch is turned on, it completes the circuit to the 120V coil of the contactor- and trips the GFCI.
Additional pics, and more details in the next entry.
