ECN Forum Forums General Topics of the Trade Non-US Electrical Systems & Trades Will an American 2-pole brkr function properly if wired to a European 220v 50h sys ?

When we had DC mains, I've read that sparkies used to fuse both legs of the circuit (positive and negative). This makes sense.

However, this practice carried over to AC where sometimes the hot and neutral were fused instead of just the hot. What happens when your "neutral" fuse blows but your "hot" fuse stays closed?

That could be a bit of a problem....from a safety point of view, especially if an ignoramus DIYer pulls the "neutral" fuse to do a repair and leaves the hot in place
