Motor Data Slide Chart

Awesome pocket reference tool for industrial electricians... Especially if yourworking with Square D motor starters... The thermal element heater sizing info is priceless... single phase and three phase motor and transformer data is fantastic TOO, along with wire size and conduit size data ...Always in my pocket.

Love that it has such a huge range of HP choices

We've had these before, quality is still great and it's a very accurate calculator for motor wire sizing, overloads and Fuse selection.

I have used this for many years. Never needs batteries, recharged nor "service" reception. fits in my pocket or tool bag, and is always right. Simply the best!

Use daily for my work

This product is jammed packed with information and convenient to use (although a little tough for older eyes to see the small print). My only issue is that when I run the numbers to see what size circuit breaker I need for a given motor, this product typically gives a completely different answer than what I get when I step through the NEC tables and calculations. The same is true for Square D’s online calculator as well. It gives the same answer as this slide chart but I wish, at least online, they would “show their math”!

Great slide card for electrical information

very helpful
