Awg To B&s [cracked] Jun 2026

: 20 AWG wire has 10 times the resistance of 10 AWG wire. Quick Reference Chart Though they are interchangeable, you'll often see B&S used in automotive or marine contexts, while AWG is standard for domestic and industrial wiring. Gauge (AWG/B&S) Typical Application Resistance (approx. ohms/1k ft) 00 (2/0) Large industrial feeders, battery cables ~0.08 2 Sub-panels, high-current circuits ~0.16 10 Large appliances (ovens, A/C units) ~1.00 12 Standard domestic branch circuits (outlets) ~1.60 14 Standard domestic lighting circuits ~2.50 18 Low-voltage lighting, electronics ~6.40 Why is the scale "backward"? The gauge number originally represented the

While AWG and B&S are the same, :

| If you see... | Do this... | |---------------|-------------| | | Buy 4 AWG. Same thing. | | AWG 2 | Use 2 B&S – identical. | | 4 B&S battery cable | OK to replace with 4 AWG. | | Metric mm² only | Convert using a proper mm² to AWG table. | | SWG | Do not match by number – use a separate SWG to AWG conversion. | : 20 AWG wire has 10 times the resistance of 10 AWG wire
