Review on 4 Post Power Distribution Block Bus Bar With Cover - Made In The USA - 250 Amp Rating - Marine by Josh Sharp

Use Anti-Seize - very small amount on threads. If heat bothers you, check it out. The rating is not displayed. I let almost 150 amps through and don't see any heat development yet. The design made it possible to pull out the plastic tire in case of fire, melting, etc. Mine is on a SOLAR photovoltaic charger with 3 large batteries. I have refractory under the article. I'll clamp the cables so I don't move if something melts. You need current and temperature readings.
