SKU: XXX-XXX-187 Categories: , Tags: ,

CSA listed RW90 type stranded copper wire. This wire is 12 AWG, normally good for 30 Amp when used in conduit with less than 3 conductors, though code requires fusing or a breaker of 20A for most applications. This wire is rated for use in dry or wet locations, raceways, or conduit. It can be used outside exposed to the weather as well, though the insulation is not 100% UV-proof and installation in conduit is recommended.

Sold by the foot! Just tell us what length you need. Available in red and black.

Please consult the Canadian Electrical Code for allowable use.
