Is there a limit to what an overhead supply can handle, loading wise?
Sorry if that sounds daft, I haven't worked with TT much in the past.
Existing house has an oven supply, no electric shower, and just your average size place with normal amount of circuits for a 3 bedroom house.
Fuse is 60/80A
A double garage is being built for a car enthusiast, he is requesting the following.
An electric garage door. ( no details as of yet )
Car Stacker Lift ( no details as of yet )
2 HP compressor
AC unit ( external condenser with one cassette inside ) ( around 4 amps )
General sockets and LED lighting.
Submain length is 45 meters.
My initial thoughts was to install a 10mm 2 core to a new DB which will be staked SPD and RCBO's
I can't see that the equipment will be used at the same time, at the most maybe the AC will be on while he is lifting a car in the air with a few general things plugged in and the lights on.
Compressor won't be used at the same time the door is being opened or a car is being lifted in the air for example.
I thought the 10mm will be ok on a 32A MCB protected by the 100ma main switch.
Now is is asking for a car charger. I have suggested a Zappy which is 7kw
So now I'm thinking of a 16mm 2 core on a 40A MCB
Your thoughts would be apreciated.
