FAQs
Q: Can T90 Nylon wires be used in wet locations?
A: No. T90 is rated for dry locations only. Use TWN75 for wet/damp environments.
Q: What distinguishes T90 from standard TW wires?
A: T90 offers a higher temperature rating (90°C dry) and oil-resistant nylon jacket.
Q: Are color-coded wires available for phase identification?
A: Yes. Standard colors include black (hot), white (neutral), and green (ground).
