Guides for this category
- THHN vs XHHW-2: which building wire to pull
THHN/THWN-2 and XHHW-2 compared: insulation, wet ratings, pulling, conduit fill and where each one belongs, with the NEC tables behind them.
- Aluminum vs copper feeders: sizing, cost and terminations
Copper and aluminum feeder sizes side by side from the 75 C column, the 200 A service example, and how to terminate aluminum so it lasts.
- Voltage drop: a worked example with NEC Chapter 9, Table 8
Calculate voltage drop by hand for a 150 ft, 16 A run, see how each wire size compares, and learn when moving to 240 V beats buying bigger wire.
- Underground wire: which types to use and how deep to bury them
UF-B, USE-2, URD and conductors in conduit for underground runs, with the minimum cover depths from NEC Table 300.5 and the rules around them.
- MC vs AC cable: grounding, where each is allowed and fittings
MC and AC armored cable compared under NEC Articles 330 and 320: the grounding path, the AC bonding strip, wet locations, support, fittings and cost.
- SER vs SEU cable: service entrance or feeder
SER and SEU compared under NEC Article 338: the bare or insulated neutral, when each may feed a subpanel, and sizing with 310.12 and Table 310.16.
- URD vs USE-2: cabled or single conductors for underground runs
URD and USE-2 compared for direct burial: cabled versus single conductors, service laterals, neutral marking and the burial depths in NEC Table 300.5.
- PV wire vs USE-2: which conductor goes in a solar array
PV wire and USE-2 compared under NEC 690.31: UL 4703 and 2 kV ratings, sunlight resistance, functionally grounded arrays and the rules by NEC edition.
