Every home needs upkeep and maintenance, especially older ones. The electrical switches and outlets are often overlooked. Although any particular outlet may not be important, if it isn’t working it’s likely a sign of a larger problem. Switches usually aren’t replaced when they should be but rather as an afterthought when they stop working altogether. Even if an electric outlet or switch is still working, there are times when you should go ahead and have them replaced.

Modern Standards

In some instances the existing switches and outlets simply aren’t up to code for what is considered adequate and safe. Older outlets may not have a ground plug but only two holes. There are adaptors available for such a problem, but they really don’t provide a proper ground like your outlet should have. With a switch, if you have to jiggle it or flip it on and off a few times for it to work, it has a bad connection and isn’t safe.

Better Quality

Simply put, newer switches and plugs are better quality than old ones and continue to develop and become even better. As long as everything is working you may not need to go out of your way to start making replacements, but when you make remodels or more extensive repairs it’s a good idea to have your electrician go ahead and replace the switches and outlets for the area he’s working in.

Ugly

Sometimes old outlets get to the point that they show their age. They can develop deep stains that won’t come clean, or perhaps they’ve been painted over the years. Worse yet are chips, scratches and cracks in the outlet or switch. Although these things are typically nothing but an eyesore, they can be a dangerous fire hazard if the damage goes into the structural aspect of the unit.

High temperatures cause conductors to expand and hence increase in length. The converse is true for low temperature conditions. The change in length varies from one conductor to another depending on its thermal expansivity. The length of copper conductors, for instance, changes by 5 feet per 1000 feet of length when the conductor temperature changes from 100 – 0°, while aluminum changes by about 7 feet. The length increases with increase in temperature and reduces with reduction in temperature.

This increase or decrease in length is of great concern when installing power transmission lines between poles and towers, or when installing other power connectors. There must be an allowance for this change in length since it can cause catastrophes if it’s not there.

Weather changes are associated with increase and decrease in temperature and thus affect power transmission lines and other conductors. However, change in temperature is only one factor that affects power lines. Below are the changes that occur to power lines and other conductors as a result of weather changes:

The amount of heat dissipated from power conductors is reduced during hot and calm weather conditions. Basically, if the temperature of air around the cable is low, more heat is lost from the cable to the air. If the air is already hot, the exchange of heat is lesser. This low heat dissipation causes the lines to overheat. However, the rise in conductor temperature (overheating) worsens when cables are transmitting too much power than required. The first effect of this increased conductor temperature is snagging, which is the downward bulging of the cable between two poles, caused by the increase in the length of cables.

Snagging is largest during extreme hot weather (largest increase in temperature) conditions experienced in summer. The increase in length results to downward bulging of the cable due to the effect of gravity. Excessive sagging is dangerous if it goes below the accepted height clearance – cables could come into contact with trees, buildings and other structures underneath, causing electrocution and fires.

Excessive sagging represent an added weight on the power line and this increase may cause the line to fail or to pull down weak poles and towers. The effects can be small but gradual and so the poles and towers will finally come down or require some adjustment/replacement after some time, which is costly. This sagging can also cause the lines to short out. Excessive sagging is also costly since it leads to increased electrical resistance. This means that a sagged power line transmits lesser current than it normally does, thus causing under-feeding of electrical equipment and industries. It is also costly and time consuming to rectify a sag.
