Something strange is buzzing around...it’s not just the hum of an electrcal transformer. As part of a new mini-series hidden by your friendly neighborhood electrician, join me on my 2025 journey to my Master Electrician license this year with some electrical themed caches as I study for the Master exams. You’ll need a sharp eye and a little courage to approach what looks like standard gear — but don’t worry, everything here is more “hide and seek” than “shock and awe" but they're "more than meets the eye" for sure.
Stealth is a must — this area sees regular traffic, both of the pedestrian and utility worker variety. Please respect the space, avoid tampering with anything live, no opening of equipment, and remember: not everything is what it appears to be. No tools required.

Sign Wave
Bright lights, big sign—this transformer hums with purpose as it powers the one of the mall's many welcome signs. This cache is part of my Master Electrician Study Series, and today’s subject is signage electrical. NEC Article 600 governs electrical signs: they must have a readily accessible disconnect within sight, proper ballast and transformer mounting, and any secondary wiring enclosed in approved raceways. This transformer likely steps down city medium voltage (likely 7 – 13.8 kV) to typical sign voltages—120v or 277v for LEDs or sometimes even 5 – 15kV for traditional neon systems.
Be safe, be kind, stay curious.
