Electrical Diagnostics | Oakland & Macomb County

The short answer

Start with the complete system and the evidence

The first visible symptom does not always identify the actual failure. Sandison documents operating condition, connected components, safety concerns, access, and the evidence needed to choose a defensible next step.

Scope and system boundary

Electrical Diagnostics begins with the installed system and the specific failure

Electrical diagnostics isolate circuits, reproduce timing when safe, measure voltage and current, inspect protection and connections, evaluate heat and load, identify upstream or utility effects, and document inaccessible or unsafe conditions. Electrical diagnosis documents the affected circuits, load and timing, breaker behavior, voltage, connection condition, heat or odor, grounding and bonding, panel and service information, equipment requirements, and any unsafe or inaccessible condition. The purpose is to identify the failed function, its effect on the property, and the accessible evidence—not to force every symptom into the same repair menu. Sandison records conditions that belong to another trade, utility, manufacturer, restoration provider, or design professional instead of hiding them inside an equipment recommendation.

Decision and verification

The electrical diagnostics recommendation should show why the next step fits

A device repair, circuit correction, load management, panel work, service upgrade, dedicated equipment circuit, or utility coordination is selected from calculated and measured demand, conductor and equipment condition, spaces, clearances, and future loads. The evidence should preserve circuit identification, relevant voltage or current observations, thermal or visual findings, connection and protection condition, load assumptions, photographs where safe, and verification under controlled operation. The written scope separates included work, permit or inspection questions, concealed conditions, owner responsibilities, exclusions, and the verification expected after completion. Availability, exact pricing, warranty coverage, and project duration are confirmed for the actual property rather than promised by a general service page.
