Hi Leecatt,
“The attached picture shows a downlight connected in an improper way, in my opinion.”
I agree with you, Those connections just look bad and I have lost lots of job’s because I quote to fit a junction box with a decent connection, where some guys will accept that. But I have to follow certain strict standards on the projects we work on otherwise my clients who have their own master electricians will make us re-do those connections in a proper way.
