True value when it comes to an electrical bus duct refers to both the price you pay for such a duct and the ongoing function of any electrical duct that you buy. Electrical ducts that fail after a short amount of time and use will have very low true value. Even if you purchase bus ducts through an surplus electrical supplier, you may discover that bus ducts have little true value. Surplus electrical equipment should only be purchased when you know that the true value of the bus ducts in question is high. High true value means that the bus ducts you pay for will continue to work long after you purchase those ducts. Furthermore, the true value of bus ducts is determined based on functionality. If you get the wrong size of a duct for your electrical system, then the true value of that duct will be minimal. Even if it is a very functional duct for one type of system, if that duct does not fit your particular system, it is of no use to you and will probably not fetch a selling price as high as the cost you paid when ordering that duct.
This leads to another true value issue when it comes to utilizing electrical equipment. Installation needs to be considered before purchasing any electrical gear. If you are able to manage installation with no professional support, meaning that you have been trained on how to install new electrical panels, ducting or other electrical components, you will be able to realize true value when you purchase the equipment you require by saving on the cost of installation. However, if you do not have the training required to manage installation of electrical equipment, the cost of installation should be considered in the overall value of those materials. You might be able to find a supplier that charges a low price for ducts, panels and other electrical gear. However, some of these affordable suppliers charge an arm and a leg for installation costs. Paying a higher price for certain electrical components has the cost of installation built in to that high price. Delivery of the components is also important. If you order a very specific type of electrical component, it may come from a manufacturer in a different state, region or even nation, so make sure you consider the cost of delivery when placing an order for any electrical items.
