Hi, can any one help me with this Low Voltage Distribution Board?
My installation a below :

17 Cooling Chamber
01 Residential building
01 Emplyees Small-Camp
20 Outdoor lamps
01 Water Submersible pump
02 Spares

All theses are supplied from Power Transformer 630kVA - 30kV/400V ( 3P+N )
This distribution board should contains :
01 Main circuit breaker
17 Circuits breakers for each chamber ( 23kW - 62kW / 40A - 105A )
01 Circuit breaker for Residential building ( 2 Floor Standard residential building )
01 Circuit breaker for Employees Small-Camp ( 4 Room, 1 Kitchen, 4 Air Conditioners )
01 Circuit breaker for 20 X Outdoor lamps ( 150W )
01 Circuit breaker for Water Submersible pump ( 6kW )
02 Circuit breakers for Spares

Thread 'RF magnetic field generation'

Hello! I want to generate an RF magnetic field at variable frequencies (from 1 to 20 MHz) using this amplifier: https://www.minicircuits.com/WebStore/dashboard.html?model=LZY-22%2B, by passing current through a loop of current (assume the inductive resistance is negligible). How should I proceed in practice? Can i directly connect the loop to the RF amplifier? Should I add a 50 Ohm in series? Thank you!
