Today I finished a refactoring task on the Subpanel GRID, and swapping out PVC conduit to EMT
Here is the inside of the Subpanel GRID. 2 AWG wire from up stream panel, and 1 AWG for downstream circuits (had extra 1 AWG so I used it)
replaced 100 amp QO panel that had 6 spaces for a
8 space QO 100 amp panel
this will allow for a total of
4 240v breakers, instead of 3. Thus giving 2 L14-30r's availability
common NEUTRAL without a NEUTRAL loop
one run of NEUTRAL to XW Pro
one run of NEUTRAL to Transfer Switch's NEUTRAL bar.
Transfer switch feeds just one NEUTRAL to critical loads panel and NEUTRAL is not 'switched'.
That is the reason for a COMMON NEUTRAL without loops
same for ground, no loops
I also am upgrading from ONE
GRID fed L14-30r receptacle to TWO L14-30r receptacles, since I have 2 Chargeverters.
I have 2, primarily for backup protection (one is none....) and for faster grid charging when needed
The XW Pro controlled automatic recharge due to LOW BATTERY only controls ONE L14-30r receptacle
and in the middle are the 2 100 amp breakers for the transfer switch and input to the XW Pro inverter
here are the 2 boxes for the 2 grid L14-30r's
the 30amp GFCI breaker and 3/4" MC flex conduit are in flight due to arrive Thursday or Friday
Notice LOCK on transfer switch. Need it, since there is no safety panel behind the front cover
To the lower right are the 2 SSR relays controlled by the XW Pro AUX contactor, for LOW BATTERY events
the grid dual L14-30r's are similar to the Generator dual L14-30r's setup
