⚡ MEDIUM-VOLTAGE TRANSFORMERS, SWITCHGEAR & SWITCHBOARDS
One contractor. The complete installation package.

At Three B Electric Inc., we do more than install electrical equipment—we handle the underground infrastructure and electrical installation together, from the ground up.

Our turnkey capabilities include excavation and trenching, underground conduit systems, vault setting, equipment-pad preparation, backfill, and compaction—along with transformer placement, switchgear and switchboard installation, conductor installation, grounding and bonding, and electrical testing.

With C-10 Electrical and Class A General Engineering licenses, plus PG&E ITS certification, we bring hands-on electrical and underground civil capabilities to the same project. That means fewer handoffs between contractors and coordinated ex*****on throughout the installation.

📸 Follow the process in our project photos: the preparation, the underground work, the equipment placement, and the electrical installation. Quality work starts long before the equipment is set in place.

We don’t just oversee projects—we work hands-on in the field every day.

Serving commercial, industrial, and residential development projects throughout Tracy and the Greater San Francisco Bay Area.

Why Zinsco Breakers Can Be Dangerous ⚠️

This is a real field condition discovered by Three B Electric Inc. during electrical work.

In this case, the breaker was not operating as expected when attempting to switch it off. A circuit breaker should protect the circuit and reliably disconnect power. When older equipment does not operate properly, it can become a serious safety concern.

This is one reason older Zinsco panels and breakers should be professionally evaluated and, depending on condition, may need replacement.

Safety Disclaimer: Electrical work can be extremely dangerous and may cause serious injury, fire, or electrocution. Do not attempt to test, remove, repair, or operate questionable electrical equipment yourself.

Always consult a qualified, licensed electrical professional. Do not try this at home.
