In some industrial environments 10kA RCDs or more are installed as 6kA arent sufficient enough for particular circuits. If not, it must be reported to building management so a decision can be made as to whether the RCD is to be replaced or retained. 4.5kA means the RCD can handle 4.5kA of fault current. Commercial and industrial RCDs rated at 6kA or more can handle 6kA of fault current. If the fault current is exceeded, the RCD will most likely be damaged and subsequently not operate as its intended. Now coming to the important question of whether commercial premises need RCD protection, the answer is yes. Periodic Inspection Reporting & Certification, Installing CT clamps in commercial premises.
