Manual transfer switch....we see lots of them on shipboard applications. I have a 150A one installed in the generator house on the island I manage; for connecting either of our power gennys to the island "grid"...
Decided to flush the gas today. Glad I did; found the air filter was shot. Literally falling apart. Got online to order a new one. Not cheap! Up to $30 for a 4x6 piece of foam with the Honda name! Found a place that had a direct replacement with a spark plug and low oil warning module for $6 plus $6 shipping. Didn't feel like doing the mask-shuffle looking thru stores to find a piece, so this works. Be here next week.
Of course you danger tagged the main open.
Are you related to Chrissy?
No, someone would have had to still be alive after invading my home to reach the main breaker. Not likely. My wife and children knew enough not to touch it.
With the many Honda clones out there, it's really hard to justify paying OEM prices. Cheap parts from China have flooded the market in the last few years. I've ordered genuine Briggs and Stratton parts, only to find out the country of origin was PRC.
