{{Menu_Sizing_and_protection_of_conductors}}

Conductors of the same cross-sectional-area, the same length, and of the same material, can be connected in parallel.<br>

The maximum permissible current is the sum of the individual-core maximum currents, taking into account the mutual heating effects, method of installation, etc.<br>

Protection against overload and short-circuits is identical to that for a single-cable circuit.<br>

The following precautions should be taken to avoid the risk of short-circuits on the paralleled cables: 
*Additional protection against mechanical damage and against humidity, by the introduction of supplementary protection 
*The cable route should be chosen so as to avoid close proximity to combustible materials<br>
