This should also be conducted at the end of thefirst six months of service if the number of operations hasnot been reached.After the first inspection, inspect at least once a year. Ifthese recommended inspections show no maintenancerequirements, the period may be extended to a more eco-nomical point. Conversely, if the recommended inspec-tion shows, for instance, heavy accumulations of dirt orother foreign matter that might cause mechanical, insula-tion or other electrical damage, the inspection and main-tenance interval should be decreased.When a breaker opens a heavy fault, at or near its rating,give it a visual inspection withdrawn from the compart-ment and with insulating barriers and arc chutesremoved.Fig. 85 Contacts and Their Adjustment: DS-416/420 Breaker.
