R613       *Electrical system must be inspectable. The PDP/PDH, associated wiring, and all circuit breakers must be visible for inspection.

R610       *1 breaker per circuit. All circuits, with the exceptions of those listed in R615 and R617, must connect to, and have power sourced solely by, a single protected 12VDC WAGO connector pair (i.e. the load terminals, as shown in Figure 9‑10) of the PDP/PDH, not the M6 cap screws.

R619       *Only use specified circuit breakers in PDP/PDH. The only circuit breakers permitted for use in the PDP/PDH are:

R621       *Protect circuits with appropriate circuit breakers. Each branch circuit must be protected by 1 and only 1 circuit breaker or fuse on the PDP/PDH per Table 9‑3. No other electrical load can be connected to the breaker or fuse supplying this circuit.
