The primary bushings on a pad-mounted transformer are called ________

Explanation:
On a pad-mounted transformer, the high-voltage connections come out through bushings, and they’re labeled to show which winding end they belong to. The two bushings that form the first primary winding are designated as H1A and H1B, with H denoting high voltage and A/B distinguishing the two ends. This naming makes it clear which bushings are the ends of the same winding and helps with correct connections to the distribution network. Alternatives like X1/X2 would be the secondary low-voltage terminals, H1/H2 without the A/B pairing isn’t the standard end-to-end labeling, and a bayonet fuse is a protective device, not a bushing.
