ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades What do you use for splicing conductors?

What do you use to splice wires together? Wirenuts? push-in connectors (like Wago)? Terminal strips in boxes? I've heard some bits here and there, but was wondering what is used where. And, have you had or seen many problems with a particular method.

Thanks in advance,
Bill
