Has anyone used Apar (appears Polish) switchgear. I just purchased a garage CU off Ebay: 40A 30mA RCD, 6A and 16A MCBs for £18. Thought it worth a punt. Enclosure was not brilliant but the RCD tested fine. 9mS @ 5X and 19mS @ rated 30mA. So seems OK. I will test the RCD after a few weeks and perhaps accidentally plug the kettle into the 6A MCB just to check.
