About Casther Electric — 20+ Years of Phoenix Pool Electrical Work

Casther Electric is a family-run electrical contractor based in Phoenix, Arizona, specializing in pool, spa, and outdoor electrical work. We hold Arizona Registrar of Contractors license AZ ROC #311594 (Specialty Dual, Active) and carry full liability insurance and bonding. Our team has over 20 years of focused experience wiring pools, replacing failing pool lights, upgrading service panels for new heaters and automation systems, installing EV chargers, and bringing power to pergolas, ramadas, and outdoor kitchens across the Valley.

Built on the National Electrical Code

Pool and spa electrical work is governed by NEC Article 680 — the most demanding section of the National Electrical Code. A loose ground, the wrong GFCI, or an unbonded handrail can turn a backyard into a hazard. We follow Article 680 to the letter on every job: dedicated GFCI protection on all pool circuits, a bonding grid that includes every metal component within 5 feet of the water, properly rated junction boxes set above the deck, and conduit runs that account for Phoenix’s heat and monsoon swings.

The People Behind the Work

You’ll work directly with our lead technicians — Omar and Junior — both reachable by phone (Tec. Omar: (480) 765-9170 · Tec. Junior: (480) 490-3980). We answer in English and Spanish, show up when we say we will, and we’d rather walk away from a job than cut a corner that puts you or your family at risk. That’s why we’re in the top 22% of all Arizona licensed contractors on BuildZoom and why most of our work comes from word-of-mouth and pool-builder referrals.
