The Stovebolt Site Forums The Shop Area The Electrical Bay Continuous Duty Relay

I've been using Bosch 87A style relays for exactly that purpose in my 49 and also in other projects that see a lot of use, without issue. The 49 has been running the switched fuses through that same Bosch relay now since 2021, now it only gets driven in the summer so not necessarily "daily" but several thousand miles (hours I can't say). In an OT LS swapped project I drive regularly, and in my plow truck, I also service all the switched fuses using the same relays. Obviously watch your particular load and use additional relays on specific circuits where it makes sense, so all the load for any given device is not necessarily going through that single switched 87A that is feeding the switched fuses, if you follow me there.
