Electrical Service in El Encanto
El Encanto is a registered Tucson neighborhood in Ward 6. Of the homes here with a published build year, the median went up in 1950 — and in electrical terms, the year a house was built tells you most of what you need to know about what is behind its walls.
When El Encanto was built
Highlighted bands are the eras that carry a known electrical issue — pre-1950 knob-and-tube, the 1965–1973 aluminum branch-circuit window, and the 1974–1989 Federal Pacific / Zinsco panel years.

Knob-and-tube and ungrounded circuits
About 47% of the homes here predate 1950. In original, un-remodeled areas that can still mean knob-and-tube wiring — no ground, not rated for modern loads, and not safe in contact with blown-in insulation. It is also why so many houses in this part of town still have two-prong outlets, or three-prong outlets with nothing behind the ground pin. Both are fixable, and neither is an emergency on its own.
Post-war services and ungrounded circuits
About 35% of the homes here went up between 1950 and 1964 — Tucson's post-war boom. Services from those years were 60 to 100 amps, often originally a fuse panel that has since been swapped for breakers without the service itself ever being enlarged. Grounded branch circuits did not become the norm until the early 1960s, so much of the original wiring in these houses is two-wire with no equipment ground, and the cloth jacket on that era's NM cable embrittles in a Tucson attic.

Neighborhood averages are a starting point, not an answer. Our free Property Electrical Profile reads the county record for one specific parcel — the build year, the assessor’s use and zoning, and the permit history — and tells you what that suggests about the service, the wiring era, and the panel.
