Frequently Asked Questions
We don’t believe in vague marketing answers. Below are straight, factual responses to the most critical manufacturing, compliance, and lead-time questions our engineers and OEM fleet clients ask before sending us their CAD files.
Do your enclosures come with an official UL or NEMA certification out of the box?
Let’s clarify the engineering reality. An empty enclosure alone typically cannot receive final UL EVSE certification until your specific electrical components are installed inside. However, we fabricate enclosures engineered specifically for rapid certification. We strictly adhere to UL 50E and NEMA 3R/4X mechanical standards. By utilizing continuous seam welds, precise gasket channels, and approved material thickness, we ensure your final assembled unit passes independent lab testing without mechanical failure.
What is your Minimum Order Quantity (MOQ)?
We are built for both agility and scale. For custom EVSE projects with production intent, our MOQ for initial prototyping is 1 unit. Once the First Article Inspection (FAI) is approved, our standard manufacturing runs typically start at 50 to 100 units to achieve optimal cost-per-part efficiency (DFM) for your procurement team.
Can you handle value-added assembly, or do you only supply bare metal?
We provide comprehensive Value-Added Assembly (VAA). To reduce your on-site labor and BOM complexity, we can pre-install polycarbonate screen covers, weather-stripping/gaskets, internal DIN rails, heavy-duty hinges, and forced-air ventilation fans before shipping. You receive an enclosure that is immediately ready for your electrical integration.
We need to protect EV chargers from weather in coastal environments. How do you ensure your enclosures are truly weatherproof and corrosion-resistant?
For coastal or highly corrosive industrial environments, standard galvanized steel is insufficient. We mandate the use of 14-gauge 316L Stainless Steel (which contains molybdenum to resist chloride pitting). We then apply a UV-resistant outdoor powder coat to a minimum thickness of 80 microns. This dual-barrier approach guarantees long-term structural integrity against heavy salt fog and humidity.
What are your realistic lead times?
For standard custom prototypes, lead times are 2 to 3 weeks from CAD approval. Upon approval of the prototype and PPAP documentation, full mass-production batches typically run 4 to 6 weeks, depending on material availability and surface finishing requirements. We provide a guaranteed delivery schedule with your formal quote.
