A Study in Success: Integrating Specialized Insulation Monitoring into a Compact Custom Enclosure

Written by ASG Power | Jul 8, 2026 3:15:43 PM

The Challenge

One of our customers, a purveyor of heavy equipment and power systems, needed more than a standard electrical assembly. The project required a compact enclosure that could support specialized Bender iso685 Series components, meet NEMA 4X requirements and manage tight internal space without existing customer-provided design files.

The Bender components added important system visibility by monitoring insulation resistance in an ungrounded electrical system, providing alarms when resistance drops below a set level and communicating values, alarms and system status to operators or monitoring systems.

Key obstacles:

Need to integrate specialized Bender insulation monitoring components

No existing customer-provided models or design files

Tight internal layout required accurate dimensions and careful component placement

Small dimensional errors could create fitment issues during assembly

Need to meet NEMA 4X requirements while supporting cost control

Production required extra attention due to limited enclosure space

Need: A partner to design, engineer and manufacture a compact enclosure solution that could integrate specialized insulation monitoring technology, reduce fitment risk and support a smoother build process.

The ASG Power Solution

We supplied the enclosure solution and engineering support needed to move the project from requirements to production. The team focused on component fit, enclosure performance, cost control and technical integration throughout the design and build process.

Our approach:

Developed an enclosure layout within the smallest practical footprint

Built a 3D model with accurate Bender component details to confirm fit, spacing and placement before production

Created a complete bill of materials to support design clarity and production planning

Selected fiberglass instead of stainless steel to reduce weight and cost

Planned internal access and assembly sequence to support efficient production

Maintained regular communication with the customer to keep the project aligned

From Vendor to Partner

Our customer needed more than a component enclosure. The opportunity was to integrate specialized monitoring technology into a compact, manufacturable electrical build.

By combining 3D modeling, component planning and practical engineering support, we helped reduce complexity and deliver a custom enclosure solution designed to support visibility, maintenance planning and operational continuity.

The Results

The final build gave the customer a compact custom enclosure that incorporated Bender iso685 Series insulation monitoring technology while meeting key space, environmental and cost requirements.

Impact:

Reduced fitment risk through internal 3D modeling before production

Supported production readiness with accurate component placement

Met NEMA 4X requirements with a cost-effective fiberglass enclosure

Integrated insulation monitoring support for greater system visibility

Helped support early warning when insulation issues arise

Completed the build despite tight internal assembly constraints
