Commercial Electrician in Co. Galway
9 businesses offering commercial electrician across Co. Galway.
Commercial electrical work differs from domestic work less in the wiring itself than in the scale of the installation and the cost of switching it off. Shops, offices, workshops, salons and small industrial units usually run on a three-phase supply, with a main board feeding sub-boards, machinery, catering equipment and lighting. Cable is more often run in visible trunking, tray or conduit than buried in walls, so that circuits can be added later without opening the building up.
The recurring jobs are new boards and sub-mains, dedicated circuits for equipment, lighting upgrades, emergency lighting, fire alarm wiring, and fault finding on premises that cannot simply be powered down. Emergency lighting and fire alarm systems have their own Irish standards, I.S. 3217 and I.S. 3218, covering design, installation, commissioning, servicing and maintenance, so they carry test and commissioning records rather than being treated as ordinary lighting. Electrical safety at a place of work also falls under the electricity provisions of the Safety, Health and Welfare at Work (General Application) Regulations 2007, which is why insurers and auditors ask for periodic inspection reports.
The registration rules are the same as in a home. A new distribution board or a new circuit is restricted electrical work under S.I. 264/2013, so it must be carried out by a Registered Electrical Contractor registered with Safe Electric, who issues a Completion Certificate against I.S. 10101. When comparing quotes, ask when the work can happen, how long the supply has to be off, and whether certification and as-fitted records are included or extra.

Common questions
Can the work be done outside trading hours?
Most commercial contractors expect to work evenings, nights or weekends, because taking a supply down during trading is usually the real cost of the job rather than the labour. Say so when requesting quotes, since it affects both price and availability, and agree in advance which circuits go off and for how long.
Does a commercial electrician have to be registered?
For restricted electrical work such as a new distribution board or new circuits, yes. It must be carried out by a Registered Electrical Contractor registered with Safe Electric, who issues a Completion Certificate confirming the work conforms to I.S. 10101. You can check registration on the public Safe Electric register before appointing anyone.
What is a periodic inspection, and do I need one?
It is an inspection and test of an existing installation, resulting in a report listing any defects and their severity. Because a commercial premises is a place of work, keeping the installation safe is an ongoing duty rather than a one-off at installation, and the report is the document insurers and auditors look for. How often it is repeated depends on the type of premises and how hard the installation is worked, so agree the interval with your contractor.
Why does my unit need a three-phase supply?
Larger motors, compressors, commercial catering equipment and machine tools are commonly three-phase, and a single-phase supply cannot run them. An electrician can confirm what the existing supply is and what the equipment actually needs. Where an upgrade is required it involves ESB Networks as well as the contractor, so it is worth establishing early because it affects the timeline more than the wiring does.
