A motor control center is only as reliable as its weakest bucket. When a bucket fails, the motor behind it stops, and in most facilities that means production stops with it. RS Breakers & Controls applies advanced manufacturing methods to MCC buckets and wrappers so that the unit you rack into your lineup works the first time, every time. Every bucket we build or rebuild is wired to specification, verified point to point, insulation tested and shipped with a documented ANSI-standard test report and a 2-year warranty.
Our shop supports the platforms Canadian industry actually runs on: Square D Model 5 and Model 6, Eaton and Cutler Hammer F10 and Freedom 2100, Westinghouse Five Star and Advantage, Allen-Bradley Centerline 2100, GE 7700 and 8000 Line, and Siemens and ITE Series 89 and Tiastar. Several of these platforms have been obsolete for years, but the motor control centers built on them are still the backbone of plants across the country. Our advanced manufacturing capability, backed by Canada's largest inventory of MCC buckets and components, keeps those lineups fully populated and fully protected.
We do more than recondition. Give us your MCC platform, bucket dimensions, NEMA starter size, disconnect type, control voltage and wiring scheme, and our shop custom-builds a bucket to your coordination requirements, combining fully tested circuit breakers or fusible disconnects from our inventory with new or reconditioned starters, overload relays, control power transformers and pilot devices. Whether you need an exact like-for-like replacement for a failed unit or a modified bucket for a new motor load, the finished assembly arrives ready to rack in and wire out.
Reconditioned buckets go through the full advanced manufacturing sequence. Bucket structures are cleaned and repaired, and stab assemblies receive the same attention we give our bus plugs: jaws re-tensioned or replaced to restore correct contact pressure onto the vertical bus, because a bucket that seats poorly becomes a hot spot in your MCC. Interlocks, unit supports and door hardware are serviced so the bucket racks, latches and isolates exactly the way the original manufacturer intended.
Every bucket is proven on the bench before it ships. Our technicians perform complete point-to-point wiring verification against the scheme, functional checks of the disconnect and starter, and insulation resistance testing on a Megger MIT520/2 5kV tester. Power path and stab connections are measured with an AEMC 5600 micro-ohmmeter to confirm low-resistance current paths, and any circuit breaker installed in the bucket has already passed through our primary injection test bay on a Phenix HC Series high current test set. The documentation for all of it ships with the bucket.
Advanced manufacturing also opens the door to targeted upgrades. We can rebuild a bucket with original-style components for exact like-for-like replacement, or modernize it with current NEMA starters, solid-state overload relays and updated control devices while keeping the bucket fully compatible with your existing MCC structure. For facilities running aging motor control centers, upgrading buckets one at a time is a practical, budget-friendly path to modern protection that avoids the cost and downtime of replacing the entire lineup.
When a bucket fails at 2 a.m., our emergency line is answered. With Canada's largest MCC bucket inventory across our Mississauga, Calgary and Saskatoon warehouses, common configurations can often ship the same day, and our shop turns custom builds around quickly when the configuration is unusual.
