When it comes to fighting for the skilled trades, Mike Rowe is THE man.

We’re excited to be partnering with mikeroweWORKS Foundation to fund work ethic scholarships and awareness for the next generation of skilled workers.

That includes the future linemen, electricians, and energy workers who keep the lights on and America running.

At Maddox, our own skilled workers remanufacture and supply transformers for critical infrastructure projects. Projects that depend on skilled tradespeople.

Overcurrent protection on a transformer above 3000 kVA?

When bayonet fuses aren’t an option, you can move fusing outside the transformer in a load interrupting switch or keep it inside with a vacuum interrupter.

Learn how vacuum interrupters work and when they make sense for your project.

When standard fusing reaches its capacity limits, you need a different way to protect your transformer. Learn how integrated vacuum interrupters compare to standalone switchgear for high-kVA applications.
