RELAY BOARD AND AUTOTRANSFORMERS Relay Board is complete Relay Board is complete Using jumper wire to bypass 2 connectors for ease of testing, will incorporate in final testing. Using jumper wire to bypass 2 connectors for ease of testing, will incorporate in final testing. Autotransformers tested and wired up properly. Ready for use in final test phase. Autotransformers tested and wired up properly. Ready for use in final test phase. Note: 264 VAC transformer actually outputting 275 at no load. Safe to assume this will lower when load is applied?
