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 8‑3. No other electrical load can be connected to the breaker or fuse supplying this circuit with the exception of devices downstream of a Kraken X60 Powerpole adapter board (WCP-1380).
