One of the most frequent questions engineers ask before inspecting RCD / Residual Current Device Trip Time & Ramp Test Report is: "Which standard should I cite on the certificate, and where do the pass/fail limits come from?" This reference guide maps IEC 60364-6 / EN 61008-1 / EN 61009-1 to national regulatory adoptions and provides the complete standard annex tables.

2. Normative Acceptance Criteria & Mathematical Basis
Evaluates Residual Current Devices (RCCB / RCBO / CBR) across 0.5x non-trip hold, 1x IΔn (0 deg / 180 deg), 5x IΔn fast disconnection, sinusoidal ramp threshold I_Δtrip, and contact voltage Uc per IEC 60364-6 §6.4.3.7, EN 61008-1 Table 1, and BS 7671 Regulation 643.8.
t_trip (1x IΔn): General <= 300 ms | Selective Type S: 130 ms <= t <= 500 ms — Maximum break time at rated residual current IΔn across both 0° and 180° half-cycles (EN 61008-1 Table 1)
t_trip (5x IΔn): General <= 40 ms | Selective Type S: 50 ms <= t <= 150 ms — Fast disconnection for additional shock protection at 5x IΔn (IEC 60364-4-41 §415.1)
I_Δtrip (Ramp): 0.50 x IΔn < I_Δtrip <= 1.00 x IΔn — Sinusoidal AC residual trip threshold window (prevents both nuisance trips and blind RCD cores)

IEC 60364-5-53 §531.3.3: RCD Waveform Selection Matrix by Connected Load (IEC 60364-5-53 / IEC 62423)
