Welcome to VoltAmpHub: Built for the Field
If you’re an electrical engineer, contractor, or panel designer, you probably know the exact headache that led me to build this site.
You’re out in the field, or sitting in front of a complicated CAD drawing, and you need to quickly verify a cable size or check a voltage drop limit. Instead of just getting the math done, you end up digging through 800-page PDFs of the NEC (NFPA 70) or IEC 60364 on a tiny phone screen, squinting to find the right derating factor for XLPE insulation. It’s a massive time-waster.
I’m a practical electrical and electronics engineer working heavily in industrial automation. After years of doing manual lookups for switchgear sizing and motor loads, I started coding my own calculators to speed up my day-to-day workflow. VoltAmpHub is basically my personal engineering toolkit, opened up for the rest of the community.
Every tool you see here—from the Electrical Load Calculator to the global Cable Sizer—is built around strict, real-world physics and global codes like BS 7671. Whether you are figuring out the main incomer sizing for a commercial building, or deciding whether to use an MCB or MCCB for a heavy 3-phase load, the goal is simple: give you accurate, safe preliminary data in seconds.
Feel free to bookmark the site for your next site visit. Poke around the calculators in the sidebar, and if there’s a specific industrial tool you’d like me to build next, just drop me a message via the contact page.

What’s up? voltamphub.com
you have very good Slipring condition monitoring system.
Hi there! voltamphub.com,
Very Amazing content specially i like this page also – https://voltamphub.com/motor-fla-calculator/
Amazing website and content is also good thank you Voltamphub
Hi friends, I’m organizing a trip to Radazul and was hoping to book a jet ski for some entertainment on the water. a tenerife? However, I keep getting varying information about whether you need a special license or previous experience to rent one here. Some booking sites say no license is essential, while others are more serious. Could anyone specify the actual rules or share official details on this? I came across this link, but would really welcome any firsthand feedback to better learn about the requirements. Thanks in ahead!
Good contents are ther helpful and amazing
