Can I add a 240V outlet for my welder in my garage?

Yes, you can add a 240V outlet for your welder in your garage, but this requires a licensed electrician and an ESA permit in Ontario. This isn't a DIY project - it involves running a new dedicated circuit from your electrical panel, which must be done by an ESA-licensed contractor.

Circuit Requirements for Your Welder

The specific circuit requirements depend on your welder's amperage draw. Most home welders need either a 30A or 50A dedicated 240V circuit. Check your welder's nameplate for the input amperage - this determines the wire gauge and breaker size needed. A 30A circuit uses 10 AWG wire, while a 50A circuit requires 6 AWG wire. The outlet type also varies: NEMA 6-30R for 30A or NEMA 6-50R for 50A welders.

Your electrician will need to assess whether your current electrical panel has enough capacity for the additional load. If you have an older 100A panel that's already near capacity, you might need a panel upgrade to 200A service. This is especially common in Ottawa's older neighborhoods where homes still have the original 100A panels from the 1960s-80s.

ESA Permit and Code Requirements

Under the Ontario Electrical Safety Code, adding any new 240V circuit requires an ESA permit and inspection. The circuit must be GFCI protected if the outlet is within 1.5 meters of a sink or in an area where water exposure is possible. However, many welders have issues with GFCI protection due to their electrical characteristics, so your electrician may install the outlet in a location that doesn't require GFCI protection per code.

The garage wiring must also meet current code standards, including proper grounding and bonding. If your garage has older wiring, this might be a good time to upgrade the entire garage electrical system to current standards.

Installation Process and Costs

A licensed electrician will pull the ESA permit, run the new circuit from your panel to the garage location, install the appropriate outlet, and arrange for ESA inspection. In Ottawa, expect to pay $600 - $1,200 for a standard welder outlet installation, depending on the distance from your panel and whether any panel upgrades are needed.
