There's no installation. Plug the single end into your existing Anderson
socket and you've got two.
Before first use, add up what you're running. Both outputs share one 50A
input, so the combined draw is what matters — not what each device draws on
its own.
This is a splitter, not a fuse. Whatever protection your circuit has now
still applies, and each branch should be fused for the load on the end of it.
Keep the contacts clean and dry. Compressed air is enough if they get dusty.
Don't leave it hanging off a socket unsupported while driving — stow it so
the connector isn't taking the weight.
