Global Power Supply operates out of a downtown Santa Barbara address, but the evidence here is thin—only two Google reviews (both five stars, neither with written comments) and sparse local footprints. One review dates back to 2020, the other to mid-2025, which tells me they're either selective about projects or don't actively solicit feedback. Their service list says "Electrical," and the project photo titles suggest diagnostic work: dead outlets, flickering lights, ground faults, arc faults, open neutrals, short circuits. That's troubleshooting territory, the kind of work that requires methodical thinking and a decent meter.
Their social presence leans corporate—LinkedIn, Twitter, YouTube, Facebook—but the recent Twitter posts I see have no content snippets, so I can't gauge whether they're sharing useful safety tips or just pushing product. The name "Global Power Supply" sounds more like a parts distributor than a residential service contractor, and I'd want to confirm they're actually doing hands-on electrical work in Santa Barbara homes versus supplying equipment to other trades. If you're hiring them, ask for local references and proof of California C-10 licensing. Two reviews isn't enough to bet your panel upgrade on.
