What Makes This Dataset Different

Troubleshooting content online is almost always a single symptom mapped to a single guessed cause. This dataset instead structures 60 symptoms with their commonly associated causes, general considerations, and an explicit risk level — so a chatbot, checklist tool, or contractor triage system can distinguish "check the photocell" from "this needs a licensed electrician" without guessing.

It is deliberately built with no step-by-step repair instructions anywhere — every record’s best-practice note says "consider checking X" or "consider a licensed electrician," never a repair procedure. See the What This Dataset Is Not section for the full safety framing.

Who Actually Uses This

Contractor CRM & dispatch tools: use risk-level and category fields to triage service calls before a technician is dispatched.

AI/RAG developers: ground a troubleshooting chatbot in structured, risk-flagged records instead of letting a model improvise a repair procedure for a live-wire symptom.

DIY homeowners: get a starting category for a symptom (“this is probably transformer-related, not fixture-related”) before deciding whether to call a professional.

I understand this is a research and organizational reference only, not electrical repair instruction. It organizes symptom categories and general considerations, and does not diagnose my specific system or tell me exactly what to do. I will consult a licensed electrician for any symptom involving line-voltage wiring, breakers, GFCI devices, grounding, or anything I am not fully confident handling safely. I understand PortfolioLighting.net makes no warranty as to the accuracy, completeness, or current applicability of any reference in this dataset.

Key Symptom Categories Covered in This Dataset

The dataset spans 60 topics; these are the recurring symptom categories most records fall under.

Transformer Symptoms

Transformer not working, buzzing, tripping breakers, and overheating — the single largest symptom category in the dataset. See Transformer Troubleshooting Overview.

Timer & Photocell Malfunctions

Common failure patterns for dusk-to-dawn photocells and scheduling timers. See Photocell Not Working.

High-Risk / Safety-Relevant Symptoms

5 of the 60 records are flagged High risk — repeated GFCI or breaker trips, grounding concerns, and suspected short circuits — and consistently point toward a licensed electrician rather than a DIY fix. See Keeps Tripping GFCI.

What This Dataset Is Not

To set accurate expectations before you buy:

Every record carries its own disclaimer field for exactly this reason — so the caveat travels with the data even if a record is extracted, filtered, or reused independently of this page.

Frequently Asked Questions

What exactly is in the Diagnostic Tree Dataset?

60 structured records organizing landscape lighting symptoms by category — transformer issues, timer/photocell malfunctions, flickering, moisture failures — with risk levels flagged, delivered as CSV and JSON.

Does this tell me how to fix my specific problem?

No. This dataset organizes symptom categories and general considerations. It deliberately does not contain step-by-step repair instructions, particularly for anything involving line-voltage wiring, breakers, or GFCI devices.

What does the risk_level field mean?

A general Low/Medium/High categorization of how safety-relevant a symptom commonly is. High is reserved for symptoms like repeated breaker trips, GFCI trips, grounding concerns, and suspected short circuits — these consistently point toward a licensed electrician.

Can I see sample data before buying?

Yes — the source-index table, live schema preview, and free sample CSV are all on this page, no purchase required for the sample.
