How do you check 240v ring circuit for overload?

To check a 240V ring circuit for overload, you can use a clamp meter to measure the current flowing through the circuit. First, ensure that all devices on the circuit are turned on to get an accurate reading. Compare the measured current to the circuit's rated capacity, typically 32A for a standard ring circuit. If the current exceeds this rating, the circuit may be overloaded, indicating the need for further investigation or remedial action.
