URD Cable Applications
250-250-3/0AWG Cable URD has a rated current capacity that depends on several factors, including ambient temperature, installation and specific conditions of use. However, The 250-250-3/0AWG have a fairly high current capacity due to their thickness and design.
The current capacity of a cable is determined taking into account the maximum allowable temperature of the conductor, heat dissipation capacity, and other safety factors. In general, This capacity is specified in tables provided by cable manufacturers or electrical engineering regulations..
