Neutral conductors running hotter than the phase conductors.

It sounds backwards. But electricians across the industry are starting to see it happen more and more.

In Episode 32 of Torque Up, we sit down with the team from Chauvin Arnoux UK (CA UK) to break down what is really happening inside modern electrical installations.

With the rise of LED lighting, EV chargers, solar systems, variable speed drives and electronic loads, the electrical systems we work on today behave very differently to the resistive systems they were originally designed for.

Harmonics, non linear loads and DC electronics are changing the way current flows through installations. In some cases this is leading to neutral conductors carrying more current than the phases, overheating cables and creating real risks if the issue goes unnoticed.

In this episode we discuss:

🟢 Why neutral conductors are overheating in modern installations
🟢 How harmonics from modern electronics are affecting electrical systems
🟢 EV chargers shutting down when voltage reaches 253V
🟢 The growing importance of power quality measurement
🟢 How electricians can protect themselves with data logging and testing
🟢 Where electrification and AI may take the industry next

This is a deep dive into the real technical challenges electricians are starting to face as electrical systems evolve.

If you are an electrician, engineer, or anyone working in the electrical industry, this episode will give you a new perspective on what is happening inside the systems we install and maintain every day.
