This diagram of a dwelling contains six errors against the AREI. Download it, open it in Trikker 2.0, correct the errors and upload the corrected file here.

How to go about it

1. Download the sample diagram with the button under the checker and open it in Trikker 2.0 with Open on the Document tab.
2. Go through the circuits one by one: the RCDs, the circuit breaker against the cross-section of the cable, the number of socket outlets per circuit and the appliances that need a circuit of their own.
3. You change a value in the properties window: select the symbol and change the property.
4. Click Save and save your project as a Trikker file (.trik).
