Reliable electrical solutions for your workplace
What Is a 3 Phase Isolator and Why Does It Matter?
A 3 phase isolator is a critical electrical safety device used to safely disconnect power from heavy machinery and equipment, such as forklift chargers, industrial plant, or commercial machinery. Unlike switching off an entire distribution board, an isolator allows specific equipment to be shut down without disrupting the rest of the electrical system.
For businesses in Oldbury, Tividale, and across the West Midlands, installing a dedicated 3 phase isolator improves safety, compliance, and operational efficiency.
The Installation Process: What to Expect
At Allen’s Ohms, every installation starts with a full assessment of your existing electrical supply and equipment requirements. This ensures the isolator is correctly rated and positioned for safe operation and ease of access.
The isolator switch and associated components are securely mounted to a solid surface. All cabling is routed through protective metal conduit and clipped neatly to prevent damage, movement, or accidental disconnection.
Safety is always the priority. Clear warning labels are applied, all earth connections are properly terminated, and the system is fully tested before being put into service.

Will installation disrupt my business?
We plan all work to minimise disruption. Where possible, installations can be carried out outside of peak operating hours to reduce downtime.
