12/2 copper NM-B cable with ground, 250 ft coil
Cable is metal-sensitive, but a trustworthy comparison must preserve wiring method, conductor material, gauge, conductor count, ground, and coil length.

Estimator worksheet
- Purchase unit
- one 250 ft coil
- Gross basis
- 250 linear ft of this exact cable per coil before routing, vertical travel, tails, slack, damaged ends, and waste
- Quantity method
- Measure reviewed circuit routes by wiring method and gauge, add declared vertical travel, tails, slack, and waste, divide by 250 ft, and round coils up while tracking verified remnants.
- Cost method
- Multiply purchase coils by the observed per-coil price. Keep boxes, devices, connectors, staples, protection, testing, labor, delivery, tax, and waste separate.
Scope checks before ordering
- Do not use this quantity record to decide conductor size, protection, ampacity, derating, or permitted installation location.
- Separate home runs and branch groups when route assumptions or required cable type differ.
Do not merge unlike products
- Do not combine aluminum, UF-B, MC, individual conductors, or different coil lengths.
- Record conductor count, ground, gauge, and package length.
- Separate contract pricing and quantity breaks from open-market prices.
Before using a price
Confirm wiring method, conductor sizing, ampacity rules, derating, installation environment, code, listing, circuit design, and permitted substitutions with the qualified electrical team.

Local price coverage
No ZIP price is published on this reference page. Record a current exact-product quote or authorized observation manually, including its source, serving market, date, package basis, availability, tax, delivery, account requirements, and validity. A future location page remains separate and evidence-gated.
