Adiabatic equation, disconnection times?
Adiabatic equation, disconnection times?
Just looking to find out where to select 't' the disconnection time for the Adiabatic formula. (This is for college not an actual install.)
Using an EN60898 breaker, 16A. Type B.
Do I look up a datasheet for the breaker?
Do I use table 41.1 in the regs book? Part of regulation 411.3.2.2 (0.4 seconds for a TN system, 230V AC)
Do I assume 0.1 seconds given the range 0.1 to 5 seconds in Fig 3A4 in the regs book?
Please explain which to use. The regs book just says 't' is the operating time...
