Steps To Consider at Design Stage Distribution Boards

Steps To Consider at Design Stage Distribution Boards Points : steps to consider at design stage distribution boards The first and foremost question when planning an installation is whither there is a supply of electricity available. If there is how near is it to the proposed building site, is it just across the road or a mile away? If it is a long distance away, what are the charges to bring it to the site and how long will it take the Supply Company to make the connection? Although most supplies are now standardized at 440 volts 3 phase a.c. and 250 volts single phase a.c., it is wise to check this. Before approaching the Electricity Supply Company, the engineer should know the approximate loading of the installation, probable future requirements, and the times when the maximum power can be supplied all the time, or whether there will not he sufficient at peak periods etc. etc. If the latter is the case, either the layout will have to he redesigned and less power consuming apparatus this could be very expensive. The generators could take over entirely from the main supply at peak periods, and at other times act as an emergency supply.

Depending on the customer’s requirements and the type and size of installation, different tariffs can be charged for electricity consumed. In small or medium size installations, such as houses, shops.
