Q: Do I need overcurrent protection fuses with my voltage indicator?

A: Most voltage indicators installed are not fused as they do not need fusing. Fusing introduces additional failure points that could lead to a false negative. Some codes or company regulations will require fusing and the indicators will function without any problem. When determined necessary, use a low .1A or .125A 600VAC fast acting fuse like KTK-1/10 or -1/8.
