Note the service entrance has only two hot wires and no ground.
Update: Some suggest metal cover but the reason I can't use metal is the grills or all the iron and enclosure are not grounded. We only use the United States two hot wires and don't use any neutral or ground. None of our appliances have any EGC. This is the reason I prefer flame retardant nonconductive panel cover. Is there any non flame retardant plastic?
In our compound we have 5 townhouses with each meter serving a house.
The panel is rusted and the cover gone. It would take us 3 weeks of power interruption to replace the whole thing because we have to apply for permit and it involves costs too and neighbors not willing. I initially thought of use cardboard to cover the breakers, but I suddenly thought what if someone would lit it with a match consindering it's outside in the street. Please suggest what kind of flame retardant nonconductive material to cover the open panel housing the breakers. Thank you.
