In the initial design steps, Electrical rooms estimated dimensions are requested. Here, we will know how to estimate the dimensions of the following electrical rooms:
- Electrical Panel Board Room,
- Transformer Room,
- Generator Room .
1- Electrical Panel Board Room
|
Step#1:
The dimensions of the electric panels are estimated either from previous projects or in accordance with the catalogs of the manufacturers.

Step#2:
After determining the number of electricity boards and their approximate dimension, the working space should be taken into consideration. According to NEC Cod minimum depth of working space is:
In a simple way:
2- Transformer Room
|
Dimensions of transformer room depend on:
1- The project country and the specifications of the installation according to the electricity company. Room dimensions must be approved from electrical company first.
2 - Is there are any low voltage or medium voltage panels in the transformer room or not?
** If the room include only one transformer we can select the room dimension according to the manufacturer catalog for example:
using the catalog of DRY - Transformers "Elsewedy Egypt"
Case#1: For indoor substation "1 transformer "
Case#2: For indoor substation "1 transformer with HV switch-gear "
Case#3: For indoor substation "2 or 3 transformer "
3- Generator Room

The dimensions of Generator room can be found Easier, through manufacturer catalogs, for example:
by using Cummins catalog:
