100a tp mccb in main panel. 25mm singles suppying a db next to main panel. Length of the singles is less than a metre. Cables are in metalic trunking. Ccc of 25mm singles in trunking is 89a. This has only been installed 5 years ago. A C2 has been given on an eicr. I myself cannot see a problem because of the length of the singles. anybody else come across anything like this.
