Nuisance breaker tripping: separate the symptom from the mechanism
An open breaker is not a diagnosis. Thermal, magnetic, residual-current and electronic trips fail for different reasons — measurement names the mechanism.

Grounding investigation in commercial buildings: path, not a slogan
Earth resistance on a drawing is not a bonding path that can carry fault current and keep touch voltage low. Measure the path you actually have.
Interpreting power-quality data: waveform first, flag second
Sag, swell, flicker and THD are labels on a capture. The job is to say which mechanism produced that shape — source, load, or the instrument setup.
Intermittent network faults: the live path, not another cable certificate
A link that drops once a shift will pass a short certification. Errors, negotiation, power and the electrical room next door are the file — not a new cord.
Building-automation network architecture: field, building, supervisory
A BAS is not one bus. Field trunks, building IP and supervisory servers differ in timing, security and ownership. Draw the layers before buying another gateway.
Coordinating BAS points and sequences before the panel lands
A points list without sequence ownership is a shopping list. A sequence without points is prose. Commissioning needs both, with a physical origin for every.
Connecting engineering applications without a weekly spreadsheet
CAD, analysis and schedules rarely share a schema. A durable bridge names objects, units and identity. A CSV emailed every Friday is a process, not an.
