I have a transfer switch that connects one of the line sides directly to the main electric meter breaker. The load side of the transfer switch goes to the interior in cement main service panel.
Due to space limitations and distance, I'm thinking of using polaris connectors for the 2 pole lines and neutral from the transfer switch load side (which also goes into the home) to mount a sub panel for a few extra circuits.
The main electric meter breaker, double pole double throw transfer switch, and interior main service panel are 125 Amps. The main cables from the meter are 2 AWG. The ground and neutral are bounded together on the main meter electrical panel.
Would this setup be ok to add a 125 Amp Subpanel on the load side of the transfer switch? I'm concerned with the neutrals in this setup.
