Predictika · Switchboard busbar orders

An AI sales agent's switchboard busbar order, checked before it goes out

An AI sales agent prepares an order for a low-voltage switchboard enclosure with its main copper busbar, and states the busbar current the order can carry. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published busbar tables and returns a verdict, every reason and the figures it computed.

Scope: Hager quadro evo switchboard enclosures and main copper busbars: enclosure size, protection rating, door type, busbar size, required current and internal weight. See everything this validator covers

This validator models enclosure and main copper busbar orders for the Hager quadro evo system, using the tables and statements in Hager's public quadro evo System Handbook, not just the scenarios shown below.

  • Enclosure size — widths of 450, 700, 900 or 1000 mm, heights of 1900 or 2100 mm and depths of 400, 600 or 800 mm.
  • Busbar and depth — copper busbars from 500 A to 4000 A; busbars larger than 1600 A need an enclosure 800 mm deep. The permissible current of each busbar is looked up for the protection rating, and the larger busbars are derated at IP43 and IP55.
  • Doors, weight and temperature — IP43 needs modular doors, the internal system may weigh at most 600 kg per enclosure, and the tables are for 35 degrees C ambient, so a higher ambient goes to a person. A stated current that disagrees with the table is blocked.

Any busbar order for these enclosures that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (none were used, so this validator produces no price build-up or line-item quote), device mounting and functional units, forms of internal separation, aluminium busbars, busbar position and interphase distances, thermal design verification, and other Hager product ranges.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
A busbar larger than 1600 A in a shallow enclosureOnly with care
The 800 mm depth requirement applies only above 1600 A, so it takes a rule tied to the busbar size, and a new busbar size means another rule to keep in step with the handbook.		The busbar and the depth are in one request and compared on every call.
A current the derated busbar cannot carryOnly with workarounds
The permissible current changes with the protection rating for the larger busbars only, so it needs a lookup per busbar and per rating rather than one rule.		The permissible current is computed for the chosen busbar and rating, then compared with the current required.
IP43 without modular doorsOnly with care
The door rule depends on the protection rating chosen, so it is a conditional rule that must be kept alongside the others.		The rating and the door type are in the same request, so the rule is checked on every call.
A stated current that disagrees with the tableOnly with workarounds
The current the agent states is free text or a separate field, so it takes an extra rule that compares it with the computed value.		The stated current is part of the request and is compared on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1Busbars larger than 1,600 A need an enclosure 800 mm deep; the 2,000 A busbar is ordered with a depth of 600 mm.
2Busbars larger than 1,600 A need an enclosure 800 mm deep; the 4,000 A busbar is ordered with a depth of 400 mm.
3The main busbar must carry 1,701 A, but the selected busbar is permissible for 1,700 A with this protection rating.
4The main busbar must carry 2,126 A, but the selected busbar is permissible for 2,125 A with this protection rating.
5The main busbar must carry 3,401 A, but the selected busbar is permissible for 3,400 A with this protection rating.
6The main busbar must carry 1,001 A, but the selected busbar is permissible for 1,000 A with this protection rating.
7IP43 protection needs the enclosure to be equipped with modular doors.
8The internal system weighs 601 kg; the handbook allows at most 600 kg per single enclosure.
9An enclosure 800 mm wide, 2,100 mm high and 600 mm deep is not a quadro evo size (widths 450, 700, 900 or 1,000 mm, heights 1900 or 2,100 mm, depths 400, 600 or 800 mm).
10An enclosure 700 mm wide, 2,000 mm high and 600 mm deep is not a quadro evo size (widths 450, 700, 900 or 1,000 mm, heights 1900 or 2,100 mm, depths 400, 600 or 800 mm).
11An enclosure 700 mm wide, 2,100 mm high and 500 mm deep is not a quadro evo size (widths 450, 700, 900 or 1,000 mm, heights 1900 or 2,100 mm, depths 400, 600 or 800 mm).
12The order states a permissible busbar current of 1,100 A; the handbook table gives 1,000 A.
13The order states a permissible busbar current of 2,000 A; the handbook table gives 1,700 A.
14The permissible currents are published for an ambient temperature of 35 degrees C around the switchboard and the handbook gives no derating table for higher temperatures; a person should confirm the busbar.
15The order states a permissible busbar current of 900 A; the handbook table gives 1,000 A.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for a low-voltage switchboard enclosure with its main copper busbar, and states the busbar current the order can carry. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published busbar tables and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote a Hager quadro evo enclosure 1000 mm wide, 2100 mm high and 800 mm deep, at IP43 protection with standard (non-modular) doors. The installation needs the busbar to carry 3000 A, the internal system weighs 580 kg and the ambient temperature is 35 degrees C. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The main busbar must carry 3,000 A, but the selected busbar is permissible for 2,720 A with this protection rating. IP43 protection needs the enclosure to be equipped with modular doors.
    6. 
      
  6. The validator returned two blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a current the derated busbar cannot carry, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the doors to modular doors.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The main busbar must carry 3,000 A, but the selected busbar is permissible for 2,720 A with this protection rating.
    12. 
      
  12. One finding cleared; still blocked on busbar cannot carry the current.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the copper busbar to 4000 A. It sets the stated permissible current as to 3400 A.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
