Nine trades, one troubleshooting partner

The AI adapts how it communicates to each trade: the terminology, the tools on hand and the way that trade works through a fault. Every answer is written for a qualified technician in that field.

Electrical

NEC-style terminology, LOTO and arc-flash awareness on any panel or conductor work. Assumes a multimeter, clamp meter, and possibly a megger.

HVAC

Refrigerant-circuit terms — superheat, subcooling, suction/head pressure — with an EPA Section 608 reminder before any refrigerant handling step.

Millwright

Mechanical alignment, bearing, coupling, and drive-train terminology. Assumes dial indicators, feeler gauges, and standard hand/power tools.

Plumbing

Pressure testing, backflow, venting, and fixture-specific terms — with a note that plumbing code varies by jurisdiction.

Logic / Control

PLC/HMI terminology — I/O, ladder logic, fault/alarm registers — without assuming a specific brand's programming software.

Instrumentation

Calibration, loop-check, and signal-type terminology — 4-20mA, HART, pressure/flow/level transmitters.

Operator

For process operators: pressure, temperature, flow and level, process logic, safety systems, interlocks and permissives, control loops, analog signals, electrical status and setpoints. Reasons from what the process is doing and what changed — and never suggests bypassing a safety system or interlock.

Mechanic

Engine, drivetrain, hydraulic, and fault-code terminology, assuming basic hand tools and possibly a scan tool.

Government / Municipality

For public works and municipal crews. Pick Government / Municipality, then your trade: the AI keeps that trade's terminology and adds the municipal way of working — rigorous safety policies, risk assessment and procedure first, heavy documentation, preventive maintenance, compliance, long-term asset reliability and public safety.
