Electrical Materials — electrical materials supplier Mississauga
Behind every lighting package is a rough-in, and GSW is the electrical materials supplier Mississauga contractors call for both. This collection is the full book: copper building wire in NMD90, T90 and RW90; steel device boxes and handy boxes; commercial-grade receptacles, switches, GFCI and dimmers; loadcentres, panelboards and breakers; safety switches and Class J fuses; dry-type and control transformers; meter sockets to Ontario utility standards; PVC and EMT conduit with every fitting; plus floor heating cable, exhaust fans, vapor barrier and interconnected smoke alarms.
Everything is CSA or cULus certified, stocked in contractor case and reel quantities, and priced at the wholesale tier — because we serve the trade, not the weekend DIY market. Pick up at our 5040 Maingate Dr counter or take flat $30 shipping to any job site in Canada.
Buying Guide
How to Choose
Build your rough-in list by system: service (meter socket, loadcentre, breakers), branch (wire, boxes, devices), raceway (PVC underground or EMT exposed), and finishing (cover plates, fans, alarms). Buying the package from one counter means one pickup, one invoice and no missing fittings on rough-in day. We bundle EMT conduit with compression connectors, and PVC with elbows, couplings and cement — ask for the complete underground or fit-out package.
Not sure what the drawings call for? Bring the spec sheet to the counter or read it to us over the phone — identifying the right wire, breaker or fuse class is a two-minute conversation.
