While renovating my house, my contractor said the 3 phase DB Box had sparks. He recommends replacing the part circled at a cost of RM500. I'm wondering if the contractor is trying to pull a fast one

Any advise if the cost is reasonable

Nope, doesn't sound right that the Neutral busbar needs to be replaced. If it is sparking why not just redo and tighten back the screw terminals? If an individual screw terminal is damaged, why not just move the slot, as you have so many empty ones?

Many thanks, stormer.lyn. notworthy.gif

Even if the contractor needed to replace it, the busbar costs less than RM50 (see link below). No way it would cost RM500
