Whose part is that anyway? No one likes having to mix and match parts to complete a job. Relying on one trusted source for all components of an underground installation makes your life easier, saves time and money during purchasing, plus potentially reduces ongoing maintenance when everything works together properly.

Power lines that are commonly seen in residential areas are not insulated and contain at least 7,000 volts. One should never be in close proximity to a power line that is hanging low or lying on the ground. Even if the line is not sparking the line is still not safe to touch or be near.

Technology advancements used by many utilities today makes reporting a power outage almost unnecessary. Smart meters and outage management systems are capable of virtually reporting your power outage for you.

It can be a challenge to identify the right elbow for varying applications. There are so many different points to consider when planning for your utility. Therefore, we put together seven simple questions to help in the process of picking the right elbow.

Elbow and parkingstand arresters are provided with a ground wire as well as a grounding eye for attaching a No.14 or equivalent drain wire. It is important to understand the correct way to install the drain wire, so that it does not negatively impact the performance of the arrester.

1. Follow all safe work practices and recommended work procedures.
2. Review instruction sheet. Form cable, with no sharp bends, to the bushing. Terminate the metallic shield (neutral) as close to the separable connector as possible. Do not expose more of the semi-con than is recommended.

Under normal conditions, elbow probes and bushing inserts should last as long as elbows. However, there are a few signs that indicate when the probe and/or bushing insert should be replaced. 

Nothing can be more aggravating when installing elbows, than the probe not wanting to screw into the connector properly. When elbow probes do not screw into the connector properly during installation, it is usually more of an alignment issue than a thread issue.
