Doing Something Wrong

[waterway]

Just got back from the Florida Keys and can't seem to figure out what I am doing wrong with this transformer hook up. It's for my RO pump and every time I replace the fuse it blows. I know its something stupid that I am missing and help would be appreciated. I guess I am still stuck on vacation mode.

Can't tell from the picture,but you are just trying to power the contactor coil with that, right?......

I don't think that's the right transformer for a car wash. I can't find any info on it with the number I can read. It certainly doesn't look like it's hooked up right, but I can't tell much by your photo.

Disconnect the wiring from the secondary on the transformer and measure the voltage going out of the transformer. If the output voltage is correct then the transformer is wired correctly and you have a short in the wiring of what ever the transformer is powering. Your transformer looks like a multitap primary so depending on what taps you are using your output voltage will change. I assume the fuse you are blowing is the one missing on the front of the transformer that protects the secondary side of the transformer?

I looked at the photo on a laptop, and when I can pick it up to tilt the screen I can read the label better. Assuming it's 240V you're connecting and not 120V, it's hooked up right. If this is for the RO pump to your bays, there shouldn't be anything drawing power until a bay is called for to run, so there's no reason the fuse should pop even if the transformer was wired wrong.

What does the small red wire go to? It almost looks like it hooks back into the primary input.
