Got one of my contactors wired up last night...works great. The first time it switched on, the mechanical *pop* startled me (when it makes the connection). I'm assuming that is the actuator you mentioned.

In that instant, I was sure I had electricuted myself, haha. But no everything is great; thanks again.

Great! Learning by doing. I'm sure you've now come to the conclusion how this this switches the power off and on to your element. When the contacts are open, no power, when closed, power. The solid Ka-chunk is good!

Haha I am very close to plugging in my control panel and testing it next week.....reading this helped keep me from "ka-chunking" in my pants when mine makes that sound. Thanks for the laugh.

Wire your 120v NEUTRAL from terminal strip to B and from D to your element outlet. - Though you really don't need a contactor on your NEUTRAL, it's up to you. It won't hurt having it.

I don't mean to start an argument but, I've been under the impression that you should never put a switch in a neutral line. I'm sure someone more fluent in electricianese can explain whether I have been mislead or not.

Generally, correct - you don't switch a neutral.

Yeah, I'm not an expert either but what you're saying makes sense...and I've heard (read) that in other places. As such, I decided not to switch any of my neutral lines. So, my contactors are double pole, but I'm only using 1 of the poles on each contactor (for the hot line).

I'm about 95% finished wiring everything up...when complete, I'll post some pictures, along with the schematic that I used as reference.

You should never switch a neutral instead of hot. That really only applys to cases that you are only switching 1 of the 2. Switching both is fine.

Note I'm not an expert either.
