Regnum Electrical specializes in process control wiring, instrumentation, and electrical systems for semiconductor fabrication facilities and advanced manufacturing environments across Maryland and the Mid-Atlantic.
Specialized electrical and controls work for environments where precision isn't optional — from fab tool hookups to complex instrumentation loops.
Design and build of custom control panels for process equipment — including PLC enclosures, I/O racks, relay logic, and motor control centers built to NEMA and UL standards.
Termination and installation of 4–20mA loops, thermocouples, RTDs, flow meters, pressure transmitters, and other field instruments critical to process monitoring and control.
Field wiring for PLC systems including I/O terminations, power distribution, communications cabling, and integration with existing fab automation infrastructure.
Electrical installation and connection of semiconductor process equipment — diffusion furnaces, CVD/PVD systems, wet benches, ion implanters, and CMP tools — to facility power and utilities.
Electrical work performed in controlled environments with experience in cleanroom protocols — proper gowning, material handling, and contamination prevention in ISO-class fab spaces.
General commercial electrical work including tenant fit-outs, power distribution, lighting, and panel upgrades for offices, labs, and light industrial facilities in the Baltimore area.
Hands-on work inside semiconductor fabrication facilities — familiar with the protocols, cleanliness requirements, and precision demands of cleanroom environments.
Specialized in instrumentation, control panel fabrication, and PLC wiring — the technical electrical work that keeps process equipment running correctly.
Fully licensed and insured in Maryland. All work is code-compliant and built to pass inspection. We serve the Baltimore area and the broader Mid-Atlantic region.
Joshua Grefe runs every project personally. You work directly with the electrician — no handoffs, no surprises, and a direct line to the person doing the work.
