Re: [RE-wrenches] Inverter bypass

2023-03-03 Thread Wallace Stahle via RE-wrenches 
I have found this Electricenter accessory part # ECSBPK01. to be very useful 
with locally available load centers.  labelled for Siemens and Murray.  Fits 
well on Eaton tho not listed for that brand.

Available locally for $32 or so lately.
Does the same thing the Generac sub panel does for the price of the interlock 
only.

For an image try:

Re: [RE-wrenches] Inverter bypass

You can also build them with the interlock kits for (almost) whatever load
center you like.  https://interlockkit.com/shop/
Some of these are UL listed, some are not.

The disadvantage of this route is that they are typically made for a high
ampacity main circuit breaker, probably overkill for most applications like
this.

Here's a 100 amp version of the Reliance box.  Cheap, lots of room, easy

I probably still have one of the old QO boxes on the shelf, but I never 
liked them.  Single pole, very tight, and you had to double lug or use a 
weird split bolt arrangement with exposed copper out past the breaker.


I started using these 60A T switches from Northern:

Midnite makes small 30A and 60A T switches as well:

Kris, It was SqD QO403, and it was a 3-pole load center/disconnect, not 
4-pole. You may recall that the dual-inverter Trace Power Panels of long 
ago used two of these, each one serving as an inverter bypass switch to 
one 120V AC leg.

I have a stand alone system that was upgraded from an FX inverter to a Radian 
WITHOUT  the companion load center.  I would like to add an inverter bypass 
circuit to operate the house on generator power.  There used to be a 4 slot 
breaker panel (SqD?) with the rocker switch preventing both breakers from being 
in the on position simultaneously.  I have not been able to find it on the 
interweb.  Anyone know of something out there that would meet my needs?
