CONSULTING FOR MANUFACTURERS

Turn installation compliance into market advantage

We are a specialist standards partner, helping electrical equipment manufacturers move from suppliers to trusted solution providers.

The current landscape

Compliance gaps are not a product problem

Electrical installation standards exist globally to protect people and property. In India, the National Electrical Code (NEC) 2023 is mandatory and forms the legal baseline for safe electrical installations. Yet real-world installations often fall short, resulting in tragic accidents.

Electrocutions and fires happen all too often and are accepted as inevitable. This is not caused by product quality. It arises from the four gaps below.

Why this matters

Unclear compliance is a commercial and reputational risk

When installation compliance is unclear, the impact on manufacturers compounds quickly.

Closing the gap

From supplier to credible technical authority

By guiding customers on how to achieve installation compliance using the right products, you move from a supplier to being viewed as a credible technical authority. This enables correct product selection, proper installation, and safer outcomes on site, while unlocking commercial value and building trust.

Clarity in electrical standards, confidence in every design

Specialist standards advisory for electrical design consultants working to achieve compliance in complex environments.

INDUSTRY REALITY

Applying standards consistently is the hard part

Compliance with electrical installation standards is critical to reduce risk and protect people and property. In India, the NEC 2023 and IS 732 are mandatory and form the baseline for safe installations.

Awareness has grown, but applying standards consistently remains difficult. It calls for detailed study of multiple interlinked standards, and performance objectives that must be interpreted, not simply followed, placing real pressure on design teams.

Design in compliance, build with confidence

We help architects and interior designers integrate electrical safety and compliance into the design process, without constraining aesthetics or function.

The current landscape

Most incidents trace back to design

In India, electrical installations are legally required to comply with the National Electrical Code (NEC) 2023, and to be designed in accordance with it before work starts.

Despite this, most incidents occur in completed, occupied buildings and are directly linked to poor design, where the electrical design is addressed late, or delegated entirely to electricians and contractors. This leads to recurring issues.

Standards-focused training

Training for the people who design, install, and verify

Standards-focused training for professionals who design, install, inspect, and verify electrical installations, delivered by specialists who help write the standards.

The industry reality

Conformity depends on competent, confident designers

Conformity with electrical installation standards is critical for electrical designers and verifiers, both from a statutory and a safety perspective. It is best achieved when design is carried out by competent professionals who understand the standard and how to apply it in real-life situations.

This is easier said than done. Standards are lengthy and hard to understand, with many cross-references that make it difficult to relate them to what is seen on site.

Who we are

The specialists who help write the standards

ProtegoPlus Electrotech is a specialist standards partner for electrical installation design, training, and conformity. We translate the standards we help write into practical, defensible guidance.

Our story

Standards expertise, from the specialists who shape them

Krish Theobald presenting at the IEC General Meeting 2025, New Delhi

Electrical installation standards exist to protect people and property. In India, electrocutions and fires happen all too often and are too readily accepted as inevitable. This is largely because there is a big gap between what standards require, and how they are interpreted and applied on the ground.

ProtegoPlus Electrotech was founded to close that gap. Through active involvement in writing electrical installation standards at the international and Indian level, we understand the intent behind each provision, not just its wording. We bring this understanding directly to designers, manufacturers, developers, and the professionals who train under us.

Every engagement we take on is measured by one thing: safer, more reliable electrical installations across India.
