The four 20A branch circuit breakers are installed on both Lines, legs. Two on L1 and two on L2.
What is the main 2 pole breaker ampere rating? I can’t read the number on the breaker handle.
Any idea the size of the feeder wires feeding the main 2 pole breaker? My guess is #6awg copper. If #4awg or larger the electrician would have installed a plastic bushing on the feeder box connector.
As for the installation and workmanship it looks good. I would have probably installed the EP-2050EE SPD straight across from the 2 pole breaker it connects to. The shorter the leads the better.
