Disconnects are an inexpensive way to connect two relatively large gauge conductors for 40-100A applications. However, most 240V disconnects only provide lugs for the two ungrounded conductors and the ground wires -- leaving no place to connect the neutral.
What's the best way to inexpensively bond the two neutrals when using 3-wire + ground cables? Large wire nuts are available, but I would prefer a lug-based connection, which seems more reliable at high currents. Polaris lugs are suitable but relatively costly. Does anyone have a more economical suggestion?
