If panel requirements are 32 amps, which transformer should be used?

Explanation:
The key idea is to choose a transformer that can supply at least as much current as the panel requires, using the smallest rating that meets or exceeds that need. If the panel needs 32 amps, you need a transformer rated at least 32 amps. The 40-amp transformer fits this requirement, providing enough capacity without being unnecessarily oversized. The 30-amp and 20-amp options are undersized for a 32-amp panel, while the 50-amp option would work but isn’t the most economical match for a 32-amp load.
