The shortest distance from Point A to Point B is a straight line, but that isn’t always the case – especially when installing wire and cable.

Sometimes, wire has to bend to connect machines and other equipment to power supplies. That means running wire or cable along poles, up walls, across cable trays, and around corners to get from one point to another. And while it might seem simple, safely installing cable means not bending it too much or too often.

As with any potentially dangerous situation, several questions must be answered before jumping in. How tightly can the copper or aluminum wire safely bend in an installation? What guidelines do we need to follow, and how can we prevent damage in the first place?

Although every wire is different, there are general guidelines to help workers safely run power through homes, businesses, and industrial locations.
