So figured I would investigate a little more now that I am at work and could look over my NEC 2011 book. There really isn't anything I can find thats a clear cut answer to this. I am going to call my rep at Tempco to day and ask the question. As I said in my earlier post. I have seen both ways, I have a system sitting here with SSR, Contactor, OverLoad. I have one here thats Contactor then SSR.
The light question is really a dozen ways to skin a cat.
wired to ssr coil:
Series - Light bulb blown, SSR coil does not get power. pros and cons? yes
Parallel - Light blown, SSR still fire but with no visual indication.
After looking at a few of my electrical drawings; I usually do the lamps in parallel as I will know if the heater isnt working due to an alarm that will be annoying me!
wired to element:
parallel - higher voltage lamp.
where do you even buy a 240v lamp?
here is a 120v LED http://www.automationdirect.com/adc/...D/ECX2052-127L
This is just my 2 cents. Everyone has there opinion and most likely have good reasons for their opinion.
