A breaker that keeps tripping, a board that runs hot, a compressor that fails early: each is written in the current before it happens. We meter the suspect circuits, name the cause with its evidence, specify the fix for your electrician, and read the circuit again after the repair.
The compressor's cold start lands on both kitchen fans and holds the 40 A circuit over its breaker. Started before the fans, with its condenser cleaned, it peaks at 30 A.
By the time equipment fails, the current on its circuit has been telling the story for weeks.
A compressor's start lengthens as its condenser fouls. A motor's running current climbs as a bearing wears. Two loads that never used to run together start to, and the breaker that carried both for years begins to trip on cold mornings.
Each of those is a pattern in the current on one circuit, and each has been seen before. Metered every minute, the circuit shows which pattern it is, when it lands and what else was running.
The restaurant here is one worked example. Change the morning and the fixes, and the breaker answers.
A start landing on another load, a circuit carrying more than it was sized for, or a breaker itself past its life. The current says which.
Phases out of balance, a loose termination, or harmonic current from drives and chargers heating the neutral. Read at the board, each has a different fix.
Running current above the nameplate, longer starts, more cycles than the duty allows. Caught on the circuit, it is a service visit rather than a replacement.
The suspect circuits metered every minute, the cause named with its evidence, the fix specified for your electrician, and the circuit read again after the repair.
Your critical boards watched, every alert checked by an engineer before it reaches you, and each one naming the board, the circuit and the likely cause.
Phase imbalance, harmonics and voltage read at the board, what each is doing to the equipment downstream, and the correction specified.
We write down the boards involved and put a meter on the suspect circuit, reading every minute.
We read the week and the worst morning, find what was running when the breaker went, and name the cause with its evidence.
We specify the fix for your electrician: what to change, on which circuit, and what it should read after.
We read the same circuit again after the repair, and a licensed engineer signs the result.
Current on the circuit that trips and on the circuits beside it, every minute for a week or more. A fault that lives in a 2-minute start is invisible at 15 minutes.
Current on each phase and on the neutral, voltage, and harmonic content, read at the board for a power quality study.
The breaker list typed from photographs of the board, and the nameplate of the equipment on each circuit, so a running current can be read against what the motor is rated for.
Loggers are fitted and collected by a licensed electrician with the panel live. For Electrical Watch the meters stay for the term of the service, and an engineer reads every alert before it reaches you.
Every minute on each suspect circuit, with what was running when the fault showed.
From the meters on the boardThe fault, the circuit it is on and the evidence for it, matched against the faults we have seen before.
Reviewed by an engineerWhat to change, on which circuit, and what the circuit should read after, written for your electrician.
Your electrician makes the repairThe same circuit read again, and the fault gone or not.
After the repairA fault study meters the suspect circuits for a week or more, every minute, and reads the panel record for the boards involved. The repair is made by your own electrician or FM partner.
Electrical Watch keeps watching the critical boards after the study, with an engineer on every alert before it reaches your dispatcher.
