We show that the transport integrals of the two-site charge Kondo circuits connecting various multichannel Kondo simulators satisfy the generalized Wiedemann - Franz law with the universal Lorenz ratios all greater than 1. The magic Lorenz ratios are directly related to the Anderson's orthogonality catastrophe in quantum simulators providing some
additional universal measure for the strong electron-electron correlations. We present a fully fledged theory for the magic Lorenzratios and discuss possible routes for the experimental verifications of the theory.
