Our Work
Benefits
Built for tomorrow
We future-proof your facility with smart diagnostics and scalable solutions. Our technicians use thermal imaging, circuit analyzers, and data logging to capture intermittent faults and surge events, then recommend upgrades like whole-facility surge protection (essential for foothill power fluctuations), networked lighting controls compliant with Title 24, and panels with space for future circuits. For sites adopting EV charging for fleets or customers, additional equipment, or backup generators, we plan capacity, grounding, and selective coordination so upgrades integrate smoothly later without rework or downtime.
Permits and compliance
Shaffer Construction handles permits and inspections end to end. We work to the 2022 California Electrical Code (based on NEC 2020), Title 24 energy standards, Very High Fire Hazard Severity Zone requirements, and applicable OSHA/NFPA 70E safety practices. Our documentation includes updated panel schedules, labeling, torque logs, and as‑built sketches where needed. We liaise with LA County Building and Safety for timely approvals and coordinate inspection walk-throughs so your repairs meet code and pass the first time.
Craftsmanship that lasts
Quality repairs start with quality materials and methods. We use copper THHN/THWN‑2 conductors, EMT or MC properly supported per code, listed connectors, and industrial-grade devices from proven manufacturers. In fire hazard zones, we use fire-rated materials and maintain required clearances. Connections are torqued to spec with calibrated tools, terminations are neatly dressed, and panels are clearly labeled for future serviceability. We test and document voltage, load balance, insulation resistance, and fault-clearing to ensure your system is safe, reliable, and ready for business.
Thoughtful, tailored planning
Every site is different. We begin with a targeted assessment, review any available single‑line diagrams, and perform load calculations where appropriate. Then we design the most efficient fix—whether that’s isolating a nuisance trip, rebalancing a 3‑phase panel, correcting a grounding defect, or upgrading protection for sensitive equipment. If capacity is tight or fire-zone upgrades are needed, we’ll propose a staged approach to minimize downtime and future-proof your operation. You approve the plan before we proceed.
Frequently Asked Questions
Do I need a permit in Altadena for small electrical repairs at my shop?+
Simple like-for-like repairs—such as replacing a faulty receptacle or breaker of the same rating—often do not require a permit. However, panel replacements, new circuits, and service changes typically do. We evaluate your scope, advise when an LA County Building and Safety permit is required, and handle the paperwork and inspection for you.
Can you work after hours to avoid disrupting my Altadena business?+
Yes. We routinely schedule evening or early-morning service for restaurants, retail, and offices along Lake and Lincoln Avenues. After-hours work helps minimize downtime and customer impact. Let us know your quiet hours and we’ll plan repairs, lockout/tagout, and testing to fit your schedule safely and efficiently.
How quickly can you diagnose and repair a tripping breaker in my workshop?+
Most troubleshooting calls are completed in 1–4 hours. We arrive with test gear to check loads, thermal signatures, insulation resistance, and power quality. Many issues—like loose terminations, overloaded circuits, or a failing breaker—are resolved the same visit. If parts or permits are needed, we can provide temporary power solutions and schedule a prompt return.
What special electrical requirements apply to Very High Fire Hazard Severity Zones?+
Properties in fire hazard zones require fire-rated materials, proper clearances from combustibles, and defensible space considerations for outdoor circuits and equipment. We ensure all repairs and upgrades meet these requirements and coordinate with LA County Building and Safety to verify compliance during inspections.
