Unwritten Guidelines for Underground Wire Installation Can Differ Greatly from one Another.

Professionals who do underground wire installation inside buildings are aware that cooperation with other professionals is necessary before you can complete the process. You must follow specific procedural rules to make sure the job runs smoothly after coordination is established and the work starts. Additionally, just because the cable installation is complete doesn't necessarily indicate the full project is. There might be a need for some post-installation operations. 

The same is true for individuals who do underground wire installation in outdoor settings, especially underground. The methods are nevertheless important even though they may be different from those used inside structures.

Here are 5 guidelines that will help assure a successful do underground wire installation draw for both novices and experienced underground cable installers:

1. Wait until all the information is on the job site before beginning the pull.

We mean by "information" about doing underground wire installation:

• A compilation of the most recent instructions or plan amendments;
• A set of plans that, if necessary, have received the fire marshal's approval;
• A copy of the specs, which will indicate whether you need a specific number of spare wires;
• A record of any change orders that might have an impact on the wire count.

2. Work with the project manager to arrange access to all restricted areas and easements.

You'll probably be able to receive a key from the property owner or general contractor if you're working on a weekend or holiday. Make sure you have every party's alternate phone number on hand in case something unforeseen occurs. Any decisions made on the job site when the project manager is not present should also be communicated to the project management.

3. Evaluate the location's job readiness:

• Determine whether any other trades will need to use the space concurrently and stake off the area you will need to operate in.
• Before you set up, go over every pull position and take the chance to implement more effective procedures for doing underground wire installation.
• Find the vaults and mark the conduits you'll be using the blueprints and specs. The purposes of the conduits are occasionally described in diagrams in the electrical part of the original designs, which are kept in the trailer of the general contractor. Keep a close eye on the details. Check change orders as well because the requirements for the quantity and size of conduits are frequently modified.

4. Spend some time making sure that all conduits are strung.

• Long delays once the job starts can be avoided by taking the time to check now. Prestringing the subterranean conduit may not be your responsibility; frequently, specifications include instructions for the electrician to install the strings.
• If the electrician is responsible for installing pull strings but they are not yet in the conduit, ask the electrical foreman when they will be.
• Utilize the time by measuring the runs if you are pulling in your string. Swab the passage with cable lubricant using a rag while you're measuring. Once you have taken measurements, be sure to record them on the plans so they may be used in the as-built drawings.
• Lay the string you use for measuring on the ground if you need to measure the conduit (or have half reels). You can determine the real cable length by laying it out between two immovable objects, such as two buildings or a building and a telephone or light pole. The cable should then be laid out in the same spot. Before you start installing the cable, you should be able to identify any errors in judgment or cable shortages thanks to this entire process.

5. Select the ideal spot for the racks.

Before doing underground wire installation avoids placing them too close to where you'll be working. When there is sufficient distance between the reels and the feeding location, the cable rolls off the reels much more effortlessly and backlashes less frequently.

• Once you've chosen the best spots, clean the area of any gravel or other objects that could harm the cable.
• Determine whether pulling from the middle or either end will be more advantageous. It is frequently simpler to draw from the middle of a long cable run in one direction, measure again, and pull from the center of the run in the opposite direction.

You can now finish the underground wire installation by extending cable into the house and garage. As wires enter the interior of the house and garage through the walls, make sure they are all enclosed inside the conduit. The next stage will be to connect the circuit breakers at the main service panel after wiring the garage's outlets and lights.

Of course, other factors affect where underground cables are placed. But if you utilize this checklist of 5 steps, you'll be well on your way to landing a good job.
