Measuring Your Dock Area to Determine Wire Length
How do I know what length of underwater wire I need?
We offer our customers a choice in wire length so that you can choose the amount of underwater wire that best suits your waterfront area. The underwater wire we use is of the highest grade and rated for permanent underwater submersion. Many of our competitors are using extension cord which is much less expensive but not rated for underwater use at all.
Because we opt for the higher quality wire, it is one of the more expensive components that go into manufacturing these systems. For that reason, give you the option to choose just the length you need to help keep our prices low. We want to help you choose the option that best fits your dock without ending up with too much or too little underwater wire.
How to Measure Your Dock
One thing that is easy to overlook is that the wire will make several turns on it’s way from the control box to the light assembly. It is important that you factor in all of these turns as they all take up length of your wire.
1. Control Box to Ground: Measure the distance from where you will mount the control box to the ground or dock level.
2. Ground to Dock Edge: Measure the distance from the ground or dock to the edge of the dock or seawall, or wherever the wire will make it’s turn toward the water. Watch for any obstacles that could divert the path of the wire.
3. Edge to Waterway Bottom: Measure from the edge of the dock down to the bottom of your waterway.
4. Light Position: Measure from the point at the bottom of your waterway in in step 3 out horizontally to where you want to place the light.
5. Light Height from the Bottom: Factor in the height that you will want the light to sit up off the bottom. In most cases this will only be a few inches to keep the light as low as possible, but you do have the option to raise it higher in the water column in excessively deep water.
It may be wise to add a few feet to your measurement to account for any measuring errors or to give flexibility when position the light in the water. If your measurements show that you need 40 feet of wire, then the 50 foot option will probably work great for you. If your measurements indicate that you will need 49 feet, you may want to consider stepping up to the 100 ft option just to play it safe. Any additional wire length left over can be neatly coiled at the side of the dock or trimmed to length.
