About Elektro Loch GmbH
Elektro Loch GmbH is an owner-managed electrical contractor from Bochum-Harpen, based at the same location at Auf der Prinz 7 since 1979. The company plans, manufactures, installs and maintains electrical systems for industrial, commercial and private customers. A key focus is industrial plant equipment: switchgear construction to customer specification with assembly and wiring in the company's own workshop, control systems for machinery and production plants including on-site commissioning, as well as electrical assembly serving as an extended workbench for plant manufacturers. In addition, the company offers recurring inspections and maintenance in accordance with DGUV Vorschrift 3, network cabling (Cat 6A) for commercial and office spaces, photovoltaic and storage systems, and wallbox and charging technology with load management. All systems are tested before delivery and handed over with a protocol; coordination with grid operators and authorities is handled by the company. The service area covers a radius of around 30 kilometres around Bochum.
