| To AJS. from EFC. X7655 EFC3/T16.2.27. AUTOMATIC SWITCH UNIT. Answering your AJS1/M15.2.27, we should think the suitably small cross section would be the equivalent of 16 SWG. with a cross sectional area of approximately .003 sq." Is this as small as you anticipated? I certainly do not think these will give rise to any trouble. EFC. | ||
