Electrical Safety Disclaimer
Last reviewed: September 11, 2026Educational information only
HomeWireHelp provides general educational explanations, planning tools, and estimates. Calculator outputs are not an inspection, design approval, permit, engineering service, or guarantee that a particular installation complies with the current Canadian Electrical Code, Ontario Electrical Safety Code, local amendments, or the rules of your Authority Having Jurisdiction.
Do not rely on a calculator alone
Real installations depend on conductor material, insulation temperature rating, raceway type, ambient temperature, bundling, voltage drop, terminations, equipment instructions, fault protection, accessibility, and local rules. Verify every design with the current code and a qualified professional before purchasing materials or energizing a circuit.
When professional help is required
Use a Licensed Electrical Contractor for service and panel work, new circuits, feeders, grounding and bonding, EV chargers, pools and spas, concealed wiring, or any job requiring a permit or inspection. Never work inside energized equipment.
