Coiling cable

Im the creepy hardscaping guy venturing into this side of the site....

So when we are on jobs and have to more heads for walkways, or add a zone or two for a new job, I have noticed a lot of guys 'coiling' up their control wires inside the clock box, and valve boxes.... is there a special tool/trick to this? Or are they just twisting it around a screw driver?


Back to the pavers........

1/2 inch pipe. It's done as a measure of safety against lightning

I've seen the control wires in the box coiled up super tight... Almost like it was wrapped around a pen. Does that sound right?

No, I've seen systems with the wires coiled like that and they were junk homeowner installed systems. Engineers that know everything but common sense.

The one really useful application of coiled wire is in a long run (100+ ft) between valve boxes. Midway between the exposed ends, you form the coil, and enclose it in a length of pipe you split, then taped back together. The reason for this is to allow for contraction of the wire in cold weather, with the enclosed coil providing slack.

It also gives you a nice coil for locating when you have a shorted solenoid. Even with a solenoid that ohms out at 0, a decent sized coil of wire will set the locator off. That and the fact that it gives you lots of slack to work with if you need to replace a solenoid are the reasons I do it.

I always understood a wire coil was to help absorb a lightning stirike.
