FAQs
What types of expertly engineered electrical switches do you supply to customers in Charleston?
We stock and custom-manufacture a wide range of switches, including toggle, rocker, push-button, rotary, selector, limit, and safety interlock models. Our catalog covers low-voltage control switches through rugged 600 V industrial-duty devices, all designed to meet or exceed NEMA, IEC, and UL standards commonly specified by commercial, marine, and industrial facilities in the Charleston area.
How can I determine which switch is best suited for my specific application?
Start by confirming voltage, current, and environmental requirements. Then factor in the number of poles/throws, actuation style, and any special certifications (e.g., NEMA 4X for washdown or ATEX for hazardous locations). Our Charleston-based engineering team offers no-cost application reviews: send us your schematic or load data, and we’ll recommend optimal switch types, contact materials, and enclosure ratings to ensure long-term reliability and code compliance.
Are your switches compliant with South Carolina and Charleston electrical codes?
Yes. All standard products carry UL or ETL listing and conform to the 2023 National Electrical Code, which the City of Charleston has adopted. For municipal, port, or historic-district jobs that require additional documentation, we supply detailed cut sheets, SCCR data, and stamped drawings to satisfy local plan reviewers and inspectors.
Do you provide installation or field support services within the Charleston metro area?
Absolutely. In addition to supplying switches, we maintain a licensed low-voltage and unlimited-voltage electrical contractor partner network in Charleston, Mount Pleasant, North Charleston, and Summerville. Our technicians can perform on-site installation, commissioning, and thermal imaging inspections, ensuring the switchgear is wired, torqued, and labeled per NEC and OSHA guidelines.
What environmental conditions can your engineered switches withstand?
Our robust product line offers solutions rated from −40 °F to 185 °F, with options for moisture, salt-spray, UV, vibration, and seismic resistance—ideal for Charleston’s coastal climate. Marine-grade stainless housings, conformal-coated PCBs, and IP66/NEMA 4X gasketed enclosures prevent corrosion and intrusion in shipyards, paper mills, and outdoor venues.
How fast can I receive switches for a project in Charleston?
Common stock items ship same-day from our North Charleston warehouse, reaching most Lowcountry job sites within 24 hours. Custom-configured or engraved switches typically ship in 3–5 business days. For urgent outages, we offer 24/7 pickup and local courier delivery to any address in Charleston County.
