Testing and production pull in different directions: a fix for electrical makers

It is the twenty-eighth. Six switchboards wait at the loading dock under tarpaulin, invoices already typed. On one, the test engineer has found a door interlock that lets the breaker truck rack in with the door open. On another, the megger shows a busbar chamber reading far below what he expects. The assembly head says the site crew can sort both. The tester refuses to sign. By evening the owner is on the phone, and however he rules, every fitter learns who truly has the last word.

This tug of war is the third pattern on the hub covering switchgear, transformer and panel works. It also surfaces on charger lines and in luminaire plants. The cure lies mostly in roles, reporting lines and goals, so it ends up on an HR desk.

• Relay secondary injection and polarity checks are clipped in the last days of the month and done in full during the first week.
• The tester signs the routine test certificate, then scribbles in the margin that the board left on instruction.
• Red-tagged boards are wheeled to a corner and loaded on a night the tester is off.
• Assembly grumbles about test delays and the bay grumbles about wiring faults, with no shared log either side trusts.
• A consultant's witness visit uncovers blank columns on test sheets the works never knew were empty.

Each board that leaves under a cloud carries risk to the client, to the factory's name and sometimes to the electricians who energise it. A slack shroud or a crossed control lead found at site costs many times the bay repair. It also arrives with an angry call from the client's engineer and a fitter's train ticket.

Inside the gate, the bill lands on the tester. One who is overruled again and again either stops tagging boards or resigns. Both outcomes leave the plant paying for a check that no longer happens.

• The tester answers to the assembly head. The person measured on tonnage shipped decides whether a red tag survives.
• Pass limits are unwritten. Megohm figures and ratio tolerances live on yellowing sheets or in one engineer's head, so every hold turns into a debate.
• Goals reward dispatch value. Bonuses, praise and the monthly meeting celebrate trucks, never first-time passes.
• Bay hours are leftovers. The test bay gets whatever time remains before the forklift arrives.
• Disputes have no route. Escalation means phoning the owner, and whoever reaches him first wins.

• To whom does the tester report, on paper and in practice?
• Does each product's test sheet print the pass limits beside each reading?
• How many boards or tanks were tagged last quarter, and who released each?
• How much of the monthly dispatch is squeezed into the final week?
• Do assembly goals mention first-time passes anywhere?

1. 1

   Write a sign-off rule per product family

   One page listing the tests, the limits, who signs, who may tag and who alone may lift a tag. The owner signs it and it is pinned in the bay.

2. 2

   Shift the reporting line

   The test role answers to a quality head or the owner, never to whoever is judged on dispatch. In a small works the owner can hold this himself. Writing roles and their authority puts it on paper.

3. 3

   Open a hold register and a caged corner

   Every doubtful unit gets a red tag, a padlocked spot and a register line: reason, date, who tagged, who released and what was done. Assembly and test read it together each Friday.

4. 4

   Book bay hours up front

   Each order carries megger, injection and ratio time set by the test lead before anyone promises a dispatch date.

5. 5

   Rewrite assembly goals

   Count units passing first time and show rework hours by stage. The process for reviews and goals builds this into appraisals.

6. 6

   Back the tester openly

   When a tag proves right, say so at the monthly meeting. When one proves wrong, review it calmly and privately.

7. 7

   Give disputes a fixed path

   A contested tag goes to one named person within hours, with the test sheet on the table, and the ruling is written down.

Unit or board number, order and client.
Test that failed or raised doubt.
Reading found, and the limit printed on the sheet.
Tagged by: name, role, date and time.
Assembly head told: name and time.
Action agreed: rework, retest or refer to the owner.
Released by: name, role and date, after retest.
Stage where the fault began: winding, core, busbar, control wiring or bought-out part.

The switchgear makers' page explains why whoever signs the report carries the risk. Its tester role note gives a tester the written right to stop a truck. The transformer version applies the idea across builds that run for weeks.
