Residential projects

The MCM Bases come in a variety of basic models (see our Selection Table) to suit the various needs for power and telecom networks. Further, the MCM cabinets can receive most types of lamp posts available on the market, as selected by the municipalities. Each of the MCM cabinets can house the power connections for 4 to 12 homes or units, depending on the selected system, and optionally the telecom connections for these clients. For areas where common trenching and joint distribution is not yet standard practice, the MCM cabinets can be used as dedicated enclosures for either power or telecom.

The following Table features typical layouts illustrating the use of the MCM Base, either as a joint or dedicated enclosure. The new MCM intermediate voltage system, the MCM-iV System is also illustrated in joint and dedicated configuration.

Integration design process in six steps

To realize the integration of power and telecom networks with the lighting system, there surely are several valid approaches. The approach recommended by MCM has been used extensively by engineering firms for the past five years and so has proven its value. We summarize here the MCM approach in a general manner, for it has to be adapted to each case since every project is unique :

1 Start with the layout of the public lighting system, as defined by the municipal standards in the selected area. This layout will either be on one side or on both sides of the street. Note that lighting at the intersections must be prioritized at all times;

2 The power and telecom public utilities also have standards which may be based on having distribution equipment on one side or both sides of the street. The light poles between the intersections will then be redistributed to match the public utilities basic requirements, namely all on one side or alternating on both sides of the street;

3 Once the basic type of layout determined (lighting, power, telecom), a load distribution design must take place, where homes or units are grouped in order to form blocks of loads. This is based on the local power utility standards on the estimated load for each type of homes (detached, semi-detached, townhouse, etc.). These blocks of loads will then define the transformers sizes and layout;

4 Then, we will assume that all of the lamp posts will be equipped with a MCM-JDP and assign two JDPs to each of the transformers, in order to minimize the homeruns lengths while connecting as many homes as possible on each JDP. For optimal result, please refer to the Standard Configurations Table. At this point, it may be considered to add hand holes where required, in strategic locations where there is no lamp post needed and power connections would be suitable, or where it is not necessary to use a JDP ;

5 Once the power and lighting layout has been planned, we may proceed to design the layout of the telephone and cable TV connections. Depending upon the technology used by each of the telecom utilities in this project (copper cables, coaxial cables, optical fibers), the MCM-JDPs will be easily adapted to the requirements of each one. However, in some locations in the project, MCM cabinets may have to be dedicated to a telecom supplier for connection equipment or amplifiers. Any unused cabinet (e.g. at the intersections) could then be put to use or some added if necessary, with or without a lamp post (optional decorative cap);

6 After the design of the various networks has been completed, empty MCM cabinets can either be removed or replaced by Retrofit Bases which look like original MCM Bases, but are installed around the lamp post(instead of installing the lamp post on top of it). The Retrofit Base has the exact same quality of doors and finish as the original MCM Base, but being non-structural, it is less expansive and does not require a Sub-base. Also, where only telecom connections are needed, the Retrofit Base can do the job more economically.
