So my dad broke the septic clean out cap with the lawn mower. He cannot find a replacement that is lower to the ground so I am printing a new one. Should I use PETG? Or another material. Also I hope this is not violating some form of regulation in the U.S.
Plugging a device into an outlet (be it a refrigerator, phone charger, or even an EV charge cord) does not require a permit. That’s normal expected use. Counters are not regulated by code. There is nothing to get a permit for in your example, and not because of the dollar amount.
Adding an outlet to support that device would to ensure proper wire gauge, space covered by the breaker, GFCI protection, and stuff like that is done correctly.
But to say that regulations don’t apply to homeowners is wrong. You likely don’t need to be a licensed electrician or plumber or whatever to work on your own home, but the regulations of what you do/how you do it almost certainly apply.
Want to bet? In my county, it is technically a requirement to pull a permit and get permission from the county government to install a window air conditioner. You know, the kind you slam the window shut on and plug into an outlet as the sum total of its “installation?” And you’re going to remove again in the fall? (Removal requires another permit.) Space heaters fall under this statute as well. Obviously the compliance rate with this is zero, but it legally gives them something to harass just about anyone over any time they feel like it.
Never underestimate the insanity of the petty egos who have small amounts of authority.
