For existing panels that need to be retrofitted with meters, the space is sometimes simply too cramped to accommodate regular CTs due to their large size, but our regular split core CTs are only about half the size and can often fit within the space of existing panels; in addition, they can be installed without even having to interrupt the power or changing the wiring. Their output is 1A instead of 5A, they are available in 100A, 200A or 300A capacities.
