Question: 2008 code bookI'm confused on the following:Article 210.21(B)(2)Does this refer to a dedicated circuit?Table 210.24 indicates that a branch circuit is permissible to have the maximum load on it based on the overcurrent protection. 15amp breaker, 15amp max. load 20amp breaker, 20amp max. load and so on...I'm I understanding this correct?Thanks

Article 210.21(B)(2)

Yes, Article 210.21(B)(2) refers to a dedicated circuit. It states:> "(2) Only those loads that are essential for the immediate care of the patient or for the operation of life-support systems shall be permitted on the branch circuit(s) required by 210.21(B)(1)."This means that, when a dedicated branch circuit is required for a patient care area, it can only supply loads that are essential for patient care or for operating life-support systems.

Table 210.24

Table 210.24 does not contradict Article 210.21(B)(2). It simply provides the maximum allowable load on a branch circuit based on the size of the overcurrent protection device.For example, a branch circuit protected by a 15-amp breaker can have a maximum load of 15 amps. This means that it cannot supply more than 15 amps of load, regardless of whether it is a dedicated circuit or not.

Conclusion

Article 210.21(B)(2) requires dedicated circuits for certain loads in patient care areas. Table 210.24 provides the maximum allowable load on a branch circuit based on the overcurrent protection device. These two requirements work together to ensure that patient care areas have reliable and safe electrical power. Flag for review
