Good Morning.
Hey the place hasn't changed a bit.
MCC Cans have two Nema 2 starters, 120 v coils, pick up current 1.91 (cold) holding current is .065
E-300's have (3) 3 amp (@120v) solid state relays, I have two E-300s in a dual motor MCC. Rewiring to create a double redundancy for overload and control.
Using the first unit, r-14 and r-24 to eneregize each of the starter contacts.
Using second unit to energize motor "A" or "B" in the event of a single motor failure.
This would create a 120 v @ .065 continuous back feed on either of the first units SSRs
Checked internet, checked Rockwells knowledge base and forum.
Best I have gotten is twice the current rating of the SSDs of the back feed (maybe) .
I do not see a leakage or doping issue, Can anyone clarify with first hand experience any short or long term problems created by this configuration
Your time and attention is appreciated. Thank you
