I’ve been running crews in Phoenix for years, and I usually have the interconnection process down to a science. But lately, APS is throwing a wrench in everything with these new UL certification requirements for line-side taps.
I’m looking at the updated 'Interconnection Application Process Guide' from May, and they’re asking for a signed letter from a UL authorized inspector on-site just to prove the tap is code compliant. Since when is the city inspection not enough? I’ve got an Associate Degree in Electrical Tech, and I’ve never seen them get this picky about a standard terminal block or piercing connector that’s already stamped.
It feels like more government-style red tape just to slow us down, especially now that the federal tax credits are gone and we’re already fighting to keep solar affordable for folks. Has anyone actually found an 'authorized inspector' who doesn't charge a fortune or take three weeks to show up? My schedule is tight and I can't have my guys sitting around waiting on more paperwork. How are you all getting past this step without blowing your budget?
