In North America, fuses are requiredto clear only their rated fuses are available for use in parallel with themain fuse. Indicator fuses can be attached to the associated fuse, or mounted separately in panel-mountedfuseclips. In addition, a push-on adapter and microswitchattachment are available, to provide remote indication.
