The fuse mountings & switches should be neat, & nicely made, & of small proportions. These remarks apply generally to the main printed board. Regarding your suggestion to put a fuse in the dynamo circuit Mr Royce says he would like a double pole fuse in the dynamo circuit & a double pole fuse in the battery circuit. There should be two single pole switches on the main board, in addition, one for the house circuit & one for the dynamo circuit; also a central zero ammeter always on the battery circuit. A further distributing board may be required for another part of the house but we will let you know about this later as soon as we know what your proposals are.
