KESCO pre-use inspection fee calculator: Checking electrical inspection fee inputs — Worked Scenario

What this scenario actually checks

Budget for the Korean private receiving-installation inspection that applies to your confirmed classification. The official 2026 table separates base fees, capacity fees and extra line items; the calculator also handles the distribution multiplier and customer-requested night/holiday surcharge. Ordinary pre-use checking is a different service and has no inspection fee.

This walkthrough focuses on checking electrical inspection fee inputs. It follows the published tool inputs, not a new formula or an automatically verified legal, financial, medical or engineering determination.

Start by preparing the right inputs

Choose confirmed low/high-voltage receiving-installation construction inspection, or ordinary pre-use checking with no fee. This does not decide legal inspection eligibility. Enter whole-kW inspection capacity. High-voltage capacity bands are ≤300, >300 and <1,000, then ≥1,000. At ≥1,000 the capacity fee accumulates 268 per first 1,000, 152 per next 99,000 and 32 per remaining kW, capped at 200,000 kW.

Before copying the example, confirm that each entered unit, date, dimension and default matches your real task. Changing only a visible number without revisiting its assumptions can change what the answer means.

• Choose confirmed low/high-voltage receiving-installation construction inspection, or ordinary pre-use checking with no fee. This does not decide legal inspection eligibility.
• Enter whole-kW inspection capacity. High-voltage capacity bands are ≤300, >300 and <1,000, then ≥1,000. At ≥1,000 the capacity fee accumulates 268 per first 1,000, 152 per next 99,000 and 32 per remaining kW, capped at 200,000 kW.
• Premises distribution doubles the capacity component. Additional poles above 5 cost 10,300 each; towers above 1 cost 45,400; underground circuits above 1 cost 50,500. Enter total counts, not excess counts.

Worked example with the calculator

Use the following input values: Low-voltage inspection; 100 kW; no extras, distribution or timing surcharge.

The example output is KRW 133,100 + VAT 13,310 = 146,410. Base 94,000 plus 100 × 391 = 133,100 before VAT.

Treat this as a reproducible example, not a result to reuse with different measurements.

What can change the answer

Premises distribution doubles the capacity component. Additional poles above 5 cost 10,300 each; towers above 1 cost 45,400; underground circuits above 1 cost 50,500. Enter total counts, not excess counts. Customer-requested night/holiday/Saturday adds 30% to base plus capacity fee, excluding extra line items. Add 10% VAT and round surcharge/VAT to whole won for the estimate. Partial/simultaneous inspections, reinspections, equipment changes and generation/PV/ESS are outside this tool.

The numerical result is valid only under the stated model and input definitions.

Before using the result for a real decision

For checking electrical inspection fee inputs, check the original measurements and input units, and save the assumptions alongside any number you share.

Where legal rules, official allowances, equipment ratings or contractual conditions matter, consult their current authoritative documents. An illustrative estimate is not a substitute for that verification.

• Reproduce the example before changing inputs
• Check all units and assumptions, including any default values
• Verify official or manufacturer-specific requirements outside the calculator
