Residential generator service rated transfer switches

[Squiggy969]

PA has just adopted the 2020 NEC. We are being told that if you install a service rated transfer switch that it must be installed outside next to the meter unless you install a disconnect instead and then feed the ATS inside. If you do not change the panel inside are other states requiring this? I know for service changes its required but is this considered a service change? Thanks

Yeah, cause there’s requirement to have your disconnects outside now I think Oregon got rid of it. I normally do that anyway but there’s been times when it’s been nice.
