A Current transformer rated 100:5 will provide a secondary current of 5 AC amperes when a single primary turn is
passed through the donut with a 100 ampere load.
The donut transformer provides additional isolation from the
conductor. The secondary leads are 2 feet long and may be extended up to 10 feet using at least 12 gauge copper
wire. If the distance is greater than ten feet, please consult the factory.
A 50:5 amp donut is the lowest rating that Simpson normally carries. A donut can be used for ratings below 50 amps
by wrapping either the primary wire passing through the core, or by wrapping the secondary wires leading to the
meter. Other ratings are available on special order.
