Call Us If…
Real situations, not a capabilities list. If one of these sounds familiar, you're in the right place.
- 01New three-phase equipment arrives and needs a supply and disconnect.
- 02A motor hums, overheats or trips — possibly a lost phase.
- 03One leg of a panel is overloaded while the others are light.
- 04A space needs three-phase service it doesn't currently have.
Three-Phase in Toronto Commercial Buildings
Most Toronto commercial buildings are supplied with three-phase power at 120/208V or 347/600V. Three-phase delivers more power on smaller conductors and runs motors smoothly, which is why commercial kitchen equipment, rooftop units, compressors and machinery often require it.
Three-Phase Work We Do
- Three-phase panels and distribution
- Equipment supplies, disconnects and connections
- Motor circuits, contactors and overload protection
- Phase balancing when panels are unevenly loaded
- Lost-phase and rotation troubleshooting
Lost Phase and Imbalance
A three-phase motor that loses one phase can run hot, stall or fail to start. Causes include a failed fuse, a breaker pole, a loose termination or an upstream fault. Unbalanced loading — too many single-phase loads on one leg — causes heat and nuisance trips. Both are diagnosed with measurements under load.
