Power to detached garage

[NewShoes]

Hi, I am attempting to trace a cable that runs from the CU in the house to a detached garage about 4 ft away from the house. My question is, is there a typical way the cable would leave the house? Would it be drilled through brick? How far underground is typical?

The house was built around 1990.

Many thanks

Is it on its own circuit or spurred off a ring main

I believe it is on its own radial circuit. It has its own breaker on the CU.

Why do you want to trace it ?

Fuse keeps blowing in CU. I've tested all items in the garage and all working fine from an extension cable so suspect the issue is with the cable that runs underground, or at least need to rule it out.

How many sockets and lights in the garage ?

 

[NewShoes]

Just one socket and 1 light. It tripped one morning when nothing was 'on' so to speak. I was only aware when I came to use the electric door

When you say 'fuse' do you mean MCB? if so they have been known to go faulty over time and are reasonably cheap to replace.

Apologies, it's not an MCB with a switch, it's a fuse which sits in a plastic housing similar to a MCB. I did attempt to buy an MCB to replace it (rather than keep blowing 15 amp fuses at 2 quid a pop) but even though I bought the same make (Hager), it didn't fit. I suspect as it's the original CU the MCB design has changed slightly over 30 odd years.

Could you post a photo of the CU?

I assume you can not visibly see it above ground anywhere? How it was installed could be anyone’s guess. What type of cable goes from the consumer unit?

I have taken a pic of the fuse carrier from the CU. Any idea which MCB I could replace this with? The 'modern' ones from Hager don't fit so I guess I'll be looking at eBay for used.

Is that faulty then?

Randomly replacing parts seldom helps

If it's an electric garage door it's power supply would always be on wouldn't it? Tried disconnecting it?

I don't think so, I just wanted an MCB so I didn't keep popping £2 15 amp fuses each time I check to see if the issue is resolved.
